Hmm...I think it was science class in 8th grade. The question was something like, 'If you threw a rubber ball and a snow ball off of the roof of a very tall building, which would hit the ground first and why?'
I'm fairly sure my answer was "The rubber ball. Duh. The friggin' snowball would melt first."
I remember him tagging a note next to that answer that said "Haha. Very funny."
