Raj: I don't like bugs, okay. They freak me out.
Sheldon: Interesting. You're afraid of insects and women. Ladybugs must render you catatonic.

Wolowitz: I think that you and Penny had a poor night.
Leonard: It wasn't poor. It was ... just fine.
Raj: Dude, the fourth Harry Potter movie was just fine.

Raj: Ooo, big talk from a man who was once treed by a chicken.

Sheldon: I am not crazy, my mother had me tested.

Sheldon: That's an inexact parallel. You and Leonard can always return to being friends, whereas I can never return to a state in which Wolowitz has not bested me like Mrs. Riley's chicken.
Penny: What's Mrs. Riley's chicken?
Sheldon: A chicken that was owned by Mrs. Riley.
Penny: Okay, forget the chicken.
Sheldon: Well, I wish I could.

Howard: What's the matter, you chicken?
Sheldon: I've always found that an inappropriate slur. Chickens are not by nature at all timid. In fact, when I was young, my neighbor's chicken got loose and chased me up the big elm tree in front of our house.
Raj: Chickens can't climb trees.
Sheldon: Thank God.
Howard: Okay, I believe the chicken made you his bitch.

Sheldon: Howard, you know me to be a very smart man. Don't you think that if I were wrong, I'd know it?

Leonard: Why would you buy peppermint schnapps?
Penny: Because I like peppermint, and it's fun to say schnapps!

Wolowitz: Sex is never the way I dreamed it was going to be.
Raj: Because in your dreams, you're a horse from the waist down.

Sheldon: Excuse me. Wolverine Origin, mini series issue two, page 22, retractable bone claws. You know, if you three spent less time thinking about sex and more time concentrating on comic books, we would have much less of these embarrassing moments.

Penny: Hey Sheldon, whattcha got there a new comic book?
Sheldon: Old comic book. I just got it from the safe deposit box.
Penny: What do you have a safe deposit box for?
Sheldon: Old comic books.

Sheldon: I lost this to Wolowitz in an ill-conceived cricket wager.
Penny: What, do they have Wii Cricket now? Well, that can't be very popular.

Leonard: I bet I could throw a rock in this room and come up with three better friends!

Sheldon: Could we focus on what's important here? I lost a bet to Wolowitz!

Raj: I wonder what the non-pathetic people are doing tonight.
