Ross Geller is a bit of the nerd of the group of Friends, but definitely a member as his sister is Monica and Chandler was his friend from college. Ross startts off as a paleontologist at the New York Museum of Natural History and later becomes a professor at NYU.
Ross is infamous for his on-and-off again relationship with Rachel, that ends with them having a kid together and mostly in the on-stage.
Of course, we can't write a bio for Ross without mentioning his three failed marriages to: lesbian Carol (who he had a kid with), Emily, and Rachel (which got annulled).
Rachel: This is about you stealing my wind!
Ross: Your wind?
Rachel: Yes, my wind. How do you expect me to grow if you won't let me blow?
Ross: You, you know I... I don't, have a, have a problem with that.
Rachel: Okay, I just, I just really need to be with myself right now. I'm sorry.
Phoebe: Uh uum, um, um.
Rachel: You're right, I don't have to apologize. Sorry. Damn it!
Ross: Rach, you know, I can see you naked anytime I want.
Ross: All I have to do is close my eyes. See? (Ross closes his eyes) Woo-hoo!
Rachel: Ross, stop that!
Ross: I'm sorry.
Rachel: Come on! I don't want you thinking of me like that anymore.
Ross: Uh, sorry. Nothing you can do about it. It's one of my, uh, rights as the ex-boyfriend. (Ross closes his eyes again) Oh yeah!
Rachel: Stop it! Cut it out! Cut it out!
Ross: Okay, okay. I'm sorry. It will never happen-- (Closes eyes again) Uh oh. Wait a minute! Wait, wait. Now there are a hundred of you, and I'm the king!
