"Teach, you auditioning for American Idol?"
I have the fortune to have a shaved head. I get judged daily by someone with a supposed witty allusion. Each student thinks s/he will be the next charming Conan O'Brien when s/he is really the next lame Jay Leno. Also, each new celebrity who shaves his or her head revitalizes the game of who can find the most obscure bald reference. You name it; I've heard it: Britney; Chris Daughtry; Natalie Portman (from V for Vendetta); Moby; Howie Mandell; and my all-time favorite, Mr. Clean.
I comeback with an allusion to what I believe will be their future places of business in life. Unfortunately for my students and fortunately for me, my allusions are completely lost on them. They're never quite sure how to respond to this comeback: "How's your day going, McDonald's?"
