While our Reduce Idiocy contest is over, idiocy has not been eradicated. As an example, I submit myself, at a recent physical.

My doctor asked me to turn my head and cough. After dropping my pants, I figured this was a good time for small talk. "I've always wondered something. Why do you have me turn my head? Does it tighten up my spine? Provide better acoustics?" I coughed left.
Satisfied, He removed his gloves. "No. It's just easier for me to do my job when you're not coughing in my face."
