Sheldon: You brought me my comic books when I wasn't feeling well. That was thoughtful.
And I was insensitive. I'm sorry.
Stuart: Thank you, Sheldon. I appreciate that.
Sheldon: And I want you to know that I mean it, you know? This isn't me just wanting to go on the trip to Las Vegas.
Stuart: What trip to Las Vegas?
Sheldon: The one everyone's taking this weekend on the party bus.
Stuart: Of course. I wasn't invited.
Sheldon: That would be my understanding. On a less painful subject, what size T-shirt do you take?

Sheldon: I caused that fight, I feel terrible. Wait, I can do that better.
I caused that fight. I feel terrible!
Yeah, wow, I don't know which one I like more.

Raj: Fine, how about this? You're making me uncomfortable by prolonging this ridiculous fight, and I wish you'd stop.
Emily: Oh, you want me to stop? No problem.
Raj: No, come on, please don't leave!
Sheldon: Point of clarification, are you still going on the trip? Because if not-
Emily: Don't worry, you're good.

Sheldon: And to memorialize this occasion, here are your commemorative T-shirts.
Howard: "Sheldon Cooper apologized to me."
Bernadette: "And he made it all better."

Sheldon: Howard and Bernadette, you tried to comfort me when I was ill, and I treated you terribly. I'm sorry.
Howard: Wow. I'm impressed.
Sheldon: No, no, no, wait. I'm not done. Allow me to underscore my sentiment with a haunting rendition of Brenda Lee's "I'm Sorry" played on the pan flute.
Howard: Apology accepted!
Bernadette: Forgiven, forgiven!
Sheldon: All right, that's eight hours of practice down the drain.

Sheldon: All you did was offer maternal care and affection, and all you received in return was rude and insensitive behavior.
Penny: Can this wait?
Sheldon: I'm afraid it can't. The trip is tomorrow. And I have more apologies to make.
Penny: Okay, fine, I accept your apology, now get out!
Sheldon: Wonderful. would you mind holding up this shirt while I take a quick-
Penny: Leonard!

Sheldon: Okay, here it comes. You tried to take care of me when I was sick, and I was mean to you. There's no excuse for that. And I'm truly sorry.
Leonard: Thank you. I appreciate that.
Sheldon: I want you to know that that is sincere. I do feel bad. I'm not just saying it to be included on your trip.
Leonard: Appreciate that, too.
Sheldon: Terrific. Now all that's left is for you to invite me to come. Me to ask, "Are you sure?" You to say, "Absolutely." And then me to bring it home with, "How could I say no to that face?"
Leonard: You're still not coming.
Sheldon: What? But I apologized and I meant it. I know that we don't play this game very often, but you're doing it wrong.
Leonard: Sheldon, I accept your apology, but you upset a lot of people while you were sick. I'm not in a position to just say you can come.
Sheldon: Well, all right. What if I apologize to all of them?
Leonard: Fine, if you apologize to everyone, they all say it's okay, then yes, you can come.
Sheldon: Challenge accepted! Sounds like it's time for the Sheldon Cooper Apology Tour.
Leonard: Well, I hope it's as much fun as the Sheldon Cooper Spell-Checks Local Menus Tour.
Sheldon: My goodness! Do you remember "comes with apsparagus"?

Sheldon: Leonard, get ready for an apology. And with the added twist of an M. Night Shyamalan movie, I'm going to mean it.
Leonard: Ah, so like every other M. Night Shyamalan movie I've seen, you spoil it in advance.
Sheldon: Hey, if you didn't know Bruce Willis was dead the whole time, that's not on me.

Sheldon: Can you believe they planned a trip to Las Vegas and didn't invite me?
Amy: Did you refuse to apologize and act like they were stupid for being mad?
Sheldon: You know, I liked it better when there was still a little mystery left in our relationship.
Amy: Everyone tried to take care of you, and you were nothing but mean to them.
Sheldon: I can't believe you're not on my side. I was on your side when someone stole your car radio.
Amy: Who else's side could you have been on?
Sheldon: I don't know. A music-loving hobo with a heart of gold?

Amy: Hi, Sheldon. What's new?
Sheldon: Our friends are jerks, and I'm mad at all of them.
Amy: I said, "What's new?" but sure.

Sheldon: Now let me see you feel bad for lying and staying in Detroit longer than you needed to.
Amy: (monotone) I feel so, so bad.
Sheldon: Hey, we're both great at this.

Amy: Sheldon, I understand that you're upset because you feel left out, but I don't know why we're even talking about this. Just apologize to them.
Sheldon: Fine, if that's what it takes to go on their dumb trip.
Amy: Maybe you could try apologizing because you actually feel bad. It's called empathy. It's something you could work on.
Sheldon: I have empathy. Watch. Leonard made me soup, and I was mean to him.
Amy: Great. Now try it as if this isn't your first day as a person.
Sheldon: Fine. Leonard made me soup, and I was mean to him. Hey, I felt a little something. Let me try again. Leonard made me soup, and I was mean to him. I was mean to him. He must have felt terrible. Oh, now I feel terrible.
Amy: Neat! Glad I could help.

Sheldon: Oh, where are we going?
Leonard: Well, Vegas, but-
Sheldon: Ugh, Atlantic City without the taffy? No, thank you.

Leonard: So, the guys and I were talking about renting a party bus and everyone going to Vegas.
Penny: Oh, that could be fun. But just to be clear, you mean a party bus with booze and music, right, not, like, juice boxes and video games?
Leonard: Yes. And Howard's birthday was a drop-off party. You didn't have to stay.

Leonard: That's fine, 'cause actually you're not invited.
Sheldon: Well, now well, that's hurtful.
Penny: Oh, Sheldon, you don't even like it there.
Sheldon: I can consider a place America's urinal cake and still enjoy the occasional visit.
