Penny: So what's going on?
Sheldon: I don't know. I looked around the room, and I saw all the faces and the presents, and it it was just too much.
Penny: I get that. Hey, you want to just bring a few people in here? You know, Wil Wheaton in the bathtub, Batman on the toilet. It'll be like the weirdest Comic-Con ever.

Leslie Winkle: Uh, in the past, I would've said something obnoxious, like, "Happy birthday, dumbass". But I'm not gonna do it. You and I have both grown a lot, and it's just so nice to see you all again. So happy birthday, Sheldon.
Sheldon: Oh. Oh, now, you know I hate change. Say it.
Leslie Winkle: Happy birthday, dumbass!

Sheldon: I don't think I can go back out there.
Penny: That's fine. You know, I hate that your sister and her friends used to torture you. But what I hate even more is, if I was there, I would have tortured you, too.
Sheldon: Based on this pep talk, I'd say you're still doing it.
Penny: My point is, there was a time I never would've been friends with someone like you, and now you are one of my favorite people. So, if what you need is to spend your birthday in a bathroom, I'm happy to do it with you.
Sheldon: Well, everyone will think I'm weird.
Penny: Sweetie, you are weird. Everyone knows you're weird, but they're all still here because they care about you so much.

Amy: We've got someone who couldn't be here but really wanted to wish you a happy birthday.
Stephen Hawking: Hello, Sheldon.
Sheldon: (gasps) Professor Hawking.
Stephen Hawking: Happy birthday to you.
Sheldon: Thank you so much. I can't believe you're-
Stephen Hawking: Happy birthday to you.
Sheldon: Oh, you're singing. Well, I'm sorry.
Stephen Hawking: Happy birthday, dear Sheldon.
Leonard: Uh, Professor Hawking, if you just give us one second, we'll light the candles, and we can all sing together.
Stephen Hawking: I was crushing it, but all right.

Raj: You know, Adam West is my favorite Batman? Well, after Michael Keaton, Christian Bale and Batman from The Lego Movie.
Howard: Don't say that to him.
Raj: What? He beat out George Clooney. And that's something. Like, I love me some Clooney.
Leonard: Don't say that to anyone.

Leonard: Sheldon, we've been together so long, it's hard to remember a time you weren't in my life. And believe me, I try.
You make me laugh.
You make me a better scientist.
You make me crazy.
You're more than just my roommate, you're my brother.
Sheldon: Thank you.
Leonard: Happy birthday, buddy.

Bernadette: I can't think of anything to say that hasn't already been said. So, here's to you, Sheldon.
Raj: Hear, hear.
Sheldon: Thank you, Bernadette. That was perfect.
Howard: What? You gotta be kidding me?

Howard: Really? You're ahead of Bale? The man who personified the words, "I'm Batman."
Adam West: I never had to say I'm Batman. I showed up. People knew I was Batman.
Everywhere I went. On the TV show, mall openings, Julie Newmar's bungalow.
Leonard: I'm sold- you're ahead of Bale.
Adam West: There's another reason I should be higher on the list. All those other guys had muscles built into their costumes. All I had in my Batsuit was 100%, grade-A West.

Leonard: So, Mother, I'm surprised you came all this way for Sheldon's birthday.
Beverly Hofstadter: Oh, I was happy to. He did come to my 60th.
Leonard: Oh, you had a party for your 60th?
Beverly Hofstadter: Oh, I wouldn't call it a party. Just a few close friends. And your sister and brother.
Penny: You know, to be fair, we did get married in Vegas and didn't invite her.
Beverly Hofstadter: And I never did thank you for that, dear.

Sheldon: Wil Wheaton, go.
Wil Wheaton: Sheldon, I know that we've had our ups and downs, but I can honestly say that my life is so much more interesting because you are in it. We may have met because you are a fan of Star Trek. But I have become a fan of Sheldon Cooper. Live long and prosper, buddy. And happy birthday.
Sheldon: That's how you do it, Wolowitz. Now you see why he's famous and you're not.

Penny: Sheldon, can I come in?
Sheldon: How do you know I'm not using the facilities?
Penny: Because you e-mail me your bathroom schedule once a week, even though I've clicked unsubscribe, like, a thousand times.

Leonard: Can I get his contact info?
Stuart: Sure, uh, but just so you know, he's kind of a diva.
Leonard: He is?
Stuart: Oh, yeah. Won't take the bus. He won't pack his own lunch. Won't let you spend the night on his couch.

Barry Kripke: (Knocking) Hello! Some of us need to check our hair because we might have a shot with Leonard's mother.

Penny: Thank you so much for helping us, Stuart.
Stuart: Oh, I was just glad to be invited. To be honest, I don't always feel like I'm part of the group.
Penny: Okay, sweetie, we're on the clock here. Can you hate yourself and frost at the same time?

Raj: Hey, so what was Adam West like on the phone?
Leonard: Uh, nice guy. But it was a little weird to hear Batman say, "Don't ring the doorbell or my poodles will go crazy."

Penny: Okay, everybody, Sheldon is gonna come back out, but I think he's a little embarrassed, so let's all be extra nice, okay?
Barry Kripke: What are you looking at me for? I'm a saint. (chuckles) But a sinner in the sack.

Amy: If I may, I'd like to propose a toast. Um, thank you all for coming tonight. I know it's customary for the birthday boy to receive presents, but I feel like I got the greatest gift the day he was born.
Everybody: Aww.
Raj: Hear, hear.
Sheldon: Amy, that was lovely. You know, this is fun. Let's do more. Someone else say something wonderful about me.

Leonard: Maybe we could get Batman to actually show up.
Raj: You mean, some guy in a lame suit?
Leonard: Or a real Batman. Hey, Stuart? Didn't you try to get Adam West to do a signing here once?
Stuart: Yeah, but there was kind of a scheduling conflict. He, uh, wanted to know when he'd get paid. And I wouldn't tell him.

Beverly Hofstadter: Sheldon, I know the future holds great things for you, and we all can't wait to see what they are. Happy birthday, dear.

Barry Kripke: Someone call Animal Control. There's a cougar on the loose.
Beverly Hofstadter: Barry, stop.
Leonard: Seriously, Barry, stop.

Penny: Yeah, what is the problem? Is it about getting older?
Sheldon: Please! Look at this porcelain skin. I'm like a human sink.

Penny: Wait a minute. You mention his birthday and he vanishes?
Leonard: Well, where's that information been this whole time?

Amy: So Sheldon, there's something I've been wanting to talk about but I know it's kind of a touchy subject.
Leonard: Way to narrow it down to everything.

Leslie Winkle: Leonard. Hey, it's been a while.
Leonard: Leslie. I can't remember the last time we talked. So much has changed.
Leslie Winkle: Has it?
Leonard: Yeah, uh, um, Penny and I got married.
Leslie Winkle: Wow, congratulations. You know, actually, I thought you'd be living with Sheldon forever.
Leonard: Yeah, .... Well, don't be a stranger.

Penny: Okay, while they get the cake, Sheldon, I just want to say, I hope you didn't think you were gonna get through tonight without a hug.
Sheldon: You know, I used to hate these hugs. Now they're just extremely irritating.

Sheldon: What is it?
Amy: Well, your birthday's coming up and you've never let us celebrate it. And I was hoping maybe this year we could.
Sheldon: Oh, I suppose that's a discussion we could have. (Sheldon runs back up the stairs)
Amy: Okay, great, I mean, it doesn't have to be a big party or anything. I was just - Where'd he go?

Sheldon: Very well. You may celebrate my life by throwing a party with cake, presents and a shower of admiration and love. But then you owe me big-time.

Adam West: Happy birthday, young man. And if any of you have enjoyed seeing me here today, I'm also available for Comic-Cons, bachelor parties, bar mitzvahs...

Leonard: Hey, uh, you know, he told a sad story about how his sister tricked him into thinking Batman was coming to his party.
Howard: That's funny. Let's do that.

Penny: All right, what about music?
Sheldon: I enjoy marching bands and Tibetan throat singing.
Penny: No music it is.

Sheldon: I know that you worked hard to put this together. I'm sorry I'm ruining it.
Penny: Oh, pl- you're not ruining it. Look, at some point, Raj will try to get everyone to do the Electric Slide. Now, that will ruin it.

Bernadette: What kind of cake do you like?
Sheldon: Well, my favorite is chocolate with strawberry frosting, three layers, and if there's writing on it, make sure it's not all caps. I don't need my dessert yelling at me.

Barry Kripke: Hello, I hope I'm not too early.
Bernadette: No, no, no. Come on in.
Barry Kripke: And how is the radiant mommy-to-be?
Bernadette: Doing great.
Stuart: You're pregnant?
Bernadette: Yeah.
Stuart: Sounds like something a member of the group might know.
Penny: Yeah, birthday party first. Pity party later.

Amy: Have to say, you you do look good in that suit.
Sheldon: Oh, thank you.
Amy: Maybe later I'll, uh, get to see you in your birthday suit.
Sheldon: But this is my birthday suit. Are you having a stroke? Because that's the kind of thing that just ruins a birthday party.

Sheldon: Thank you. That was wonderful.
Penny: Oh, wait, wait, wait. Stuart didn't get to speak.
Stuart: Oh, oh, okay. Um. Uh, Sheldon, I've spent most of my life feeling invisible, but having you and everyone-
Amy: Hey, everybody, listen up.
Penny: (To Stuart) You nailed it.

Howard: Sheldon, I don't think everyone-
Sheldon: Wolowitz, perfect. Everyone listen to Wolowitz.
Howard: Okay, then, uh, Sheldon, we've known each other a long time. And it is a pleasure to work with you and call you my friend.
Sheldon: Little generic. Keep thinking. We'll circle back.

Amy: Okay, so how do you feel about party balloons?
Sheldon: Uh, Mylar balloons, yes. Latex balloons, no. Water balloons, I will jump off the roof and aim for your car.

Raj: Thank you! That's why I say Keaton's number one. He brought a sense of humor to the role.
Adam West: Oh, if you're gonna factor in a sense of humor, then I should be at the top of the list. It should be me, Keaton, Kilmer, Lego, Bale, and that pretty boy Clooney.

Howard: Can we just all agree we're worried about Affleck?
Raj: Sure.
Leonard: Yeah, of course.
Adam West: What's an Affleck?

(After Sheldon runs out of his party)
Adam West: I still get paid, don't I?

Sheldon: Uh, um uh, thank you all so much for coming. Uh, Beverly. Wil Wheaton. Adam West, for some reason.
Leonard: Batman finally came to your party.
Adam West: Happy birthday, Sherman.

Leonard: Ready when you are, Professor Hawking.
Stephen Hawking: And a one, and a two.
All: Happy birthday to you. Happy birthday to you. Happy birthday, dear Sheldon. Happy birthday to you. (to you.)

Amy: But it's the one day a year that's just all about you.
Leonard: One day. (Laughs) Right.

Penny: You know, if you had a party now, you have plenty of friends that would love to come.
Leonard: And we live here, so we have no choice.
Penny: Yeah.

Amy: You realize none of those things would happen now?
Sheldon: I do, but why do you care if I celebrate my birthday at all?
Amy: Well, you made my last birthday so memorable, I wanted to return the favor.

Penny: Well, where is he?
Amy: Sheldon?
Leonard: I'll check his room.
Sheldon: Surprise!
Penny: Oh, my God!
Sheldon: Just one example of how birthdays can be terrible. Now, can we please drop this subject and pick a new one? Yeah, I suggest "how thick can a soup get before it becomes a stew?" You know, the answer, it may surprise you.

Amy: Can you please just tell me why?
Sheldon: Fine. As you know, I have a twin sister with whom I obviously share a birthday. Every year we'd have a party. No one I invited would ever come, because they didn't like me.
Amy: I'm sorry.
Sheldon: Oh, that part wasn't so bad. I didn't like them, either. But then I'd inevitably spend the whole day being tortured by my sister's friends.
Penny: Oh, you poor thing.
Sheldon: When I was six, they told me Batman was coming to my party. I waited by the door for hours. Closest thing to Batman I saw was when a robin flew into the window.

Adam West: So, who's taking me home?

Raj: And it was Gandhi who said, "Live as if you were to die tomorrow. œLearn as if you were to live forever."
Sheldon: And it was Sheldon Cooper who said "Let's speed this up. A lot of people want to talk."

Leonard: Okay, I'd better go in there and talk to him.
Amy: Well, don't you think I'm the one who should go in?
Leonard: No offense, but I've known the guy a really long time.
Amy: Well, I've, you know, seen him without pants on.
Leonard: Again, no offense, but so have I.
Amy: Well, he's seen me without pants on.
Leonard: Again, -
Penny: Okay, this is ridiculous.

Amy: Are you all right?
Sheldon: No, I just I got a little light-headed.
Amy: Oh, d-do you need a minute?
Sheldon: No. No, if I can walk past that pet shop with the parrot in the window, I suppose I can do this.

Sheldon: Is there a reason I had to leave my own apartment?
Amy: Well, I think they just want you to see it for the first time all decorated.
Sheldon: But who's gonna tell them they're doing it wrong?
Amy: Well, I'm sure they'll ask you to give a speech, and that's when you just tear 'em a new one.

Howard: You have any idea what you're getting Sheldon for his birthday?
Raj: He's been fascinated with dinosaurs lately. Maybe we could get him a fossil.
Leonard: Well, just don't get anything Jurassic. He feels like that whole chunk of time has gone Hollywood.

Leonard: Are you crazy? How can you put Michael Keaton in front of Christian Bale?
Adam West: Oh, please. Even my poodles know Bale's overrated.
