Dr. Gallo: Wow, you really do have a lot on your plate.
Penny: I do. You know, Leonard's right. Talking to you is really helping.
Dr. Gallo: Oh, I'm glad. You know, you might also benefit from a prescription for anxiety.
Penny: Okay, if you think it'll help. Oh, just don't make it Placinex. I do not need sudden fits of homicidal rage.

Stuart: (watching Howard and Bernadette sleep) I really miss this.

Leonard: Guys, tickets already went on sale.
Sheldon: What?
Howard: They're not supposed to be available yet.
Leonard: I don't know what to tell you, but they're already available.
Raj: Wait, are you sure they're Star Wars tickets?
Leonard: No, it's Steel Magnolias 2: Even Steelier.

Sheldon: All right, this goes against everything I stand for, but desperate times call for desperate measures. (Kneels down to pray) Lord, this is Sheldon Cooper, you're good friends with my mom. I know I've spent my life denying that you exist-
Howard: Got them!
Sheldon: -and I will continue do so!

Penny: I'm really happy that you and Amy are back together.
Sheldon: Thank you.
Leonard: I'm also really happy, but I can't pretend it's for you. New Star Wars in three days!

Sheldon: Thursday can't get here soon enough. I'm taking off work to watch the original trilogy while I eat enough Star Wars cereal to choke a wookie.

Penny: Sweetie, you do realize Thursday is Amy's birthday?
Sheldon: And you do realize I bought my ticket when Amy and I were broken up. I hope you didn't need anything in that case, because it's closed.

Penny: You guys just got back together. You might not want to ditch her on her birthday.
Leonard: I think Penny has a point. You can see it another day.
Sheldon: But someone might spoil the movie. No one can spoil Amy's birthday for me. Surprise, she's even older. Who saw that coming?
Penny: Aww, that's nice. Put that on her cake.

Professor Proton: Oh, great, this again.

Sheldon: Oh, Arthur, what brings you back?
Professor Proton: Beats me. I just hope this is not a sex dream.

Sheldon: In the past, you've come to me when I was struggling with a dilemma.
Professor Proton: And the one time when you were afraid and you needed me for a night light.

Professor Proton: And can I get out of this mumu now?
Sheldon: Those are the robes of the Jedi, the guardians of peace and justice in the galaxy.
Professor Proton: And they don't wear underwear.

Sheldon: Where are you going?
Professor Proton: I don't know, but hopefully somewhere I can wear pants.

Amy: Sheldon, what's wrong?
Sheldon: I wanted to let you know I'll be spending your birthday with you.
Amy: Okay.
Sheldon: See, I had tickets to the Star Wars premiere that night, but Professor Proton came to me in a dream, dressed as Obi-Wan Kenobi, and convinced me that I should be with you.
Amy: Obi-what?
Sheldon: I'll let you get back to sleep now. Good night.
Amy: Good night. Uh, Sheldon, were you actually not going to spend my birthday with me?
Sheldon: (feigning sleepiness) It's late, gotta go, bye.

Raj: Good for Sheldon, deciding to stay with Amy on her birthday.
Leonard: I know. It's still gonna be weird to see the movie without him.
Howard: We could wait a couple of days and see it together.
*All three laughing*
