When a customer slid into the barber chair, the barber asked him how he wanted his hair cut.
"Make it short," the customer replied, "with a bare patch above my left ear, but longer on the right side so that it covers my right ear. I also want my left sideburn above my left ear and the right sideburn below my right ear."
The barber looked puzzled and said, "I don't think I can do that."
The customer replied, "I don't know why not--that's the way you cut it the last time I was here!"
