The scene is from the movie "Footloose." Rock and roll blares from a tape deck parked on the hood of a car while actor Kevin Bacon demonstrates all the right moves for his rhythm-impaired friend Christopher Penn so that he won't be humiliated at a high school dance. You might watch this film at home on a slow night. Richard Sarkin, M.D., on the other hand, uses the movie clip with its dance lesson to teach physicians how to teach.
