JULIE: Ow, look at my hand from the gym.
DAVE: What did you do?
JULIE: I don’t know, I think it’s like a burst blood vessel or something. How am I doing this to myself?
DAVE [loftily]: How would I know? I’ve never had a problem. [Holding out hands] See? I have perfect weightlifting technique.
JULIE: What’s this on your hand right here?
DAVE: That’s from a hammer.
