This comes via my mate Noel:
Billy was at school one morning when the teacher asked all the children what their fathers did for a living.
All the typical answers came out, fireman, policeman, salesman, chippy, captain of industry etc, but Billy was being uncharacteristically quiet so the teacher asked him about his father.
"My father is an exotic dancer in a gay club and takes off his clothes in front of other men. Sometimes if the offer is really good, he'll go out with a man, rent a cheap hotel room and let them sleep with him."
The teacher quickly set the other children some work and took little Billy aside to ask him if that was really true.
"No," said Billy, "he plays cricket for England but I was just too embarrassed to say."
