I can write binary, I can balance mallets on my fingers. I can balance mallets on each other. I can twirl mallets all the way around my fingers, multiple times. (I still haven't beat the timpani player that could make his mallets fly in circles between his middle and ring fingers. That was l33t)
I can write in mirror!cursive, too.
Oh, I can get an A in mr. cato's pre-ap class. That's probably the rarest of any I mentioned.
