Mine:

Girl: Du know it's scientifically proven that left-handers live a shorter life than right-handers.

Boy: Really? Then how long would I live?

Girl: Aren't Du left-handed?

Boy: Huh? I'm ambidextrous.

Girl: ??? But I see Du use your left hand when writing.

Boy: It's just for writing, and maybe a few other things, but see, I read, shower, play the Piano and everything else with both hands!! Isn't that a sign that I'm ambidextrous?

Girl: No, it's a sign that Du lack common sense.
