A man orders a bowl of soup in a nice restaurant. When the waiter delivers it to his table, the man notices the waiter is sticking his thumb in the soup. The guy says to the waiter "What the fuck? Why do you have your thumb in my soup." The waiter explains that he has injured his thumb and the doctor ordered him to keep it warm. "
"Why don't you stick it up your fucking ass then" the irate customer yells at the incompetant waiter.
To which the waiter replies, "what do you think I do when I'm in the kitchen?"
