Howard: I'm proud of you, Leonard. Working out on the North Sea for months, that's really something.
Leonard: I know. As far as science goes, this is the adventure of a lifetime.

Leonard: It's not a competition.
Howard: You're right, you're right. I'm really proud of you, and I'm gonna miss you when you're gone. And space beats water.
