Quote from Chandler in The One with the Donor
Monica: Chandler, this is crazy. Well, what did you even say to him? "Come up. Meet my wife. Give us your sperm." Chandler: No. I invited him to dinner so you'd get a chance to get to know him. I mean, if we go through a sperm bank, you never meet the guy, get to check him out. Monica: Chandler. Chandler: I'm telling you, he's great. I mean, even if my sperm worked fine, I think he'd be the way to go.
