During my high school math class this one student-athlete would draw pictures of Teenage Mutant Ninja Turtles on the dry erase board every day. The Turtles, as a franchise, were dated even back then. He was quite good at it and could bang them out in a few minutes each. I was never sure which ones he was drawing since all the dry erase markers were blue. There was a quiet dignity to his movements while making the fast drawings, and our teacher tolerated them. Then one day the kid used a Sharpie to make his drawings. They stayed on the board through all the classes for the next week until our custodian installed a new board. Of all the strange tics you could have in life, I find drawing Ninja Turtles to be one of my favorite.
