A man goes into his regular barber shop, sits down at the chair and the barber ask him how he would like his hair cut this time.
The customer replied, "Well, lets see. Leave the left side long, take quite a bit off the right side to make it really short. I want the very back to have a mohawk and the front and top to be spotty and irregular."
The barber was astonished and said he could not cut hair that way.
"Why not," the customer replied, "you cut it that way last time!"
