Little David was in his 5th grade class when the teacher asked the children what their fathers did for a living. All the typical answers came up: fireman, policeman, salesman, dentist, lawyer, carpenter, and so forth.
David was being uncharacteristically quiet, and then the teacher remembered that poor little David's father had died a year earlier, so the she tactfully asked him about his mother.
"My mother is an exotic dancer and she takes off her clothes in front of other people and she wiggles around and they put money in her underwear and sometimes if a man makes a really good offer Mom brings him to our house and she has sex for money."
The teacher, obviously shaken by this statement, hurriedly set the other children to work on another project, and took little David aside to ask him, "Is that really true about your mother?"
"No," said David, "my mother really works for Senator John Kerry, but I was too embarrassed to say that in front of the other kids."
