You should feel good about yourself, but inflated egos are dangerous things. Ah. Well, I'll trust you.
How exactly do you prank yourself? It sounds complicated. All I did was swap out the music we use to warm up at the barre to with a vinyl copy of Los del Rio's Macarena. It was riskier than it sounds. Our instructor is very uptight. He never suspected it was me, of course, and unless he stumbles upon this network I doubt he'll find out it was me, but I count the prank as a success. It had the whole class doing the Macarena instead of tendus and plies.
