Air guitar is a popular pastime. Miami's Kendrick Norton added a new wrinkle to the fun by inventing leg guitar.
After sacking James Blackman, the Hurricanes defensive tackle used the Florida State quarterback's leg as a prop. He's lucky not to have been penalized for taunting or unsportsmanlike conduct, but there's no rule that says a player can't use an opponent as a make-believe musical instrument.
Norton probably would have run into more trouble for suggestively dancing to his imaginary solo.
