Howard: Are you listening to yourself?
Sheldon: I always listen to myself. It's one of the great joys of my life.

Sheldon: Okay, stop ruining Valentine's day and order my pizza.

Kripke: You guys ever use any toys?
Sheldon: I do have a model rocket next to my bed.
Kripke: A rocket? You're a freak! I love it!

Sheldon: I haven't seen Raj in several days. Is he no longer part of our social group? And if so, should we be interviewing for a replacement? Perhaps this time we go Latin.

Howard: Come on, we could have a pants party! Go put some on!

Raj: Later, losers!

Penny: Hey! Shouldn't you be out with your gang spray painting equations on the sides of buildings?

Raj: Doesn't anyone have a rod of resurrection? Because if you've got one, I need it bad. Get in here with your rod and give it to me.
Stuart: Okay, you need to say these things in your head before you say them out loud.

Raj: Ooh! Girls' night, girls' night. Ooh, ooh!
Stuart: How does he not hear that?

Raj: What's wrong with people? Why don't they stop?
Sheldon: Maybe we're better off. What if we were to get in a car with a crazy person?
Leonard: Look at us, Sheldon. We're the crazy people!

Raj: Are they actually arguing about comic books?
Leonard: No, that can't be right.
Howard: Maybe "Thor's Hammer" is a new color of nail polish.

Bernadette: What kind of comics do the guys like?
Stuart: Um, a little bit of everything. Mostly superhero stuff.
Amy: All right, well, who's the best superhero?
Stuart: Shh! You can't ask a question like that in here. Are you trying to start a rumble?

Raj: And we're blending, and we're blending, and we're done. Sheldon: I know Mr. Data isn't supposed to smile, but here it comes. Howard: (Dressed as a Borg) Come on, guys. Let's do this. Leonard: (dressed as Captain Picard): Yeah, I'm sweating my bald cap off.

Leonard: What kind of a person steals another person's car in broad daylight?
Sheldon: What kind of person leaves his keys in the car?
Leonard: I thought we agreed this was all Koothrappali's fault.
Sheldon: You're right. (To Raj) Nice going.

Cop: You guys need me to call someone? I'm guessing your moms?
Leonard: Thanks, but we've got it covered.
Howard: Okay, I just talked to my mom.
