Raj: Shut your ass.

Amy: The meme has reached full penetration.
Sheldon: Pun intended?
Amy: No. Happy accident.

Amy: I should let you know that she asked for details about our dalliance.
Sheldon: Interesting. So it went beyond the mere fact of coitus to a "blow by blow" as it were.
Amy: Pun intended?
Sheldon: I'm sorry. What pun?

You see evil everywhere.

Grace: (to Rigsby) Be yourself.
Cho: Yeah, don't do that.

Erica

Cho

Talk to me when your ex-husband remarries someone ten years younger and two sizes smaller.

Kim

Maybe she escaped one animal only to fall prey to another.

Sara

Spends her life helping others dodge punches, but she couldn't dodge this one.

Sara

You know, it's not how you come into this world that counts. It's how you live it.

Doc Robbins
