Friends, Season 2

Phoebe:
Okay, y'know there's a lot of things I don't believe in, but that doesn't mean that they aren't true. Like...the Bermuda Triangle. Or crop circles. Or evolution.

Ross:
Whoa, whoa...you don't believe in evolution?

Phoebe:
Nope, not really.

[Phoebe reaches for a plate of cookies, Ross moves the plate away]

Ross:
You don't believe in evolution?!

Phoebe:
No, I think it's a good story... y'know, Darwin, monkeys... but I just don't buy it.

Ross:
Evolution is not something for you to buy, evolution is scientific fact, like, like, like the air we breathe, like gravity.

Phoebe:
Oh, okay - don't get me started on gravity.

Ross:
You, uh, you don't believe in gravity?

Phoebe:
Well, it's not so much that, you know, like I don't believe in it, you know, it's just... I don't know. Lately I get the feeling that I'm not so much being pulled down as I am being pushed.

[They hear a knock at the door.]

Chandler:
Uh-oh. It's Isaac Newton, and he's pissed. Quick, Pheebs, up on the ceiling!
