Big Bang Theory Quote
Penny: How do you know Leonard?
Dr. David Underhill: I'm a physicist.
Penny: (laughing) No, you're not.
Dr. David Underhill: Why is that so surprising?
Penny: Well, it's just that the physicists I know are indoorsy and pale.
Leonard: I'm not indoorsy. I just wear the appropriate sunblock because I don't take melanoma lightly.
