Sheldon: Are you still mad at me?
Leonard: Yes. We missed our lecture, we were almost arrested, and you got me locked in a room with a man who forced his tongue down the throat of a stuffed Wookiee.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

Howard: Don't feel bad. Some day someone will be throwing out your work, too.
Leonard: That someone was Sheldon and the day was yesterday.

Sheldon: I remember the song! It's called "Darlin'" by the Beach Boys! Oh, thank goodness! I'm not crazy! I don't have to take a pigeon as my bride!
Leonard: There goes our shot at him living on the roof.

Amy: Have you made a decision about the TARDIS? I think I can sell it if we call it Big British Portapotty.

Sheldon: Amy, the Daleks are right on my tail. Quick, we need to reset the time circuits. Oh no, I left my Sonic Screwdriver behind.
Amy: Really should have thought this through.

Howard: Come on, one day this may double in value and be worth half what I paid for it!
