An overweight man was waiting in line at a bank. There were two teenage boys in line behind him.
They were giggling and making fun of how fat the man was. After five minutes of this the man turned to the boys and asked them politely to stop, as he couldn't help his weight problem.
With this the boys asked: Oh, and why are you so fat Mister?
The Man turned around and replied: "Well, every time I screwed your mother, she gave me a cookie."
