Touching My Body Of Music

(This story comes from the beginning of this century. Our lecturer told us the following story to keep us from trying to hide radios, mp3 players, etc. under our desks and listening to them through ear-buds:)

Lecturer: “[Student], I can see you bopping your head to the music! Turn it off.”

Student: “I swear I’m not listening to music.”

Lecturer: “You have one hand under your desk and a big smile. If you’re not playing with a music player, what are you playing with?”
