I tried to scare an Indian with a snake. Come on, Cooper, you're better than this.

Sheldon

Leonard: Well, it wasn't my fault.
Sheldon: The implication being that you somehow tripped and fell into her lady parts?

Sheldon: Is there any reason you're keeping this dead goldfish?
Penny: Damn, I forgot to feed him and that I had him.
Sheldon: Well, now, did you also have a dog? Because I found what appears to be a battery-operated chew toy.
Penny: Party's over. Party's over.

Wolowitz: Okay forgot giant ants. How about giant rabbits?
Raj: Big or small, I don't like rabbits. They always look like they're about to say something, but they never do.
Sheldon: Rabbits do have a respiratory system that would support great size. And as a side note, they are one of the few animals whose scrotum is on the front of the penis.
Raj: Maybe that's what they want to talk about.

Sheldon (singing)

You think that's bad. In college, I passed out at a frat party and woke up with more clothes on.

Amy

Does the elastic woman in "The Incredibles" use birth control or can she actually be a diaphragm.

Raj

Wolowitz: You love that spot.
Sheldon: No, I love my mother. My feelings for my spot are much greater. It is the singular location in space around which revolves my entire universe. And now it's yours.

Raj's poem

Sheldon: I'll have a diet Coke.
Penny: Can you please order a cocktail? I need to practice mixing drinks.
Sheldon: Fine... I'll have a virgin Cuba Libre.

Sheldon: Yes, and would you make it diet?
