With thanks to Big Bubba, who emailed me this joke:
A fourth-grade teacher asked the children what their fathers did for a living. All the typical answers came up - fireman, mechanic, businessman, car salesman... and so forth.
However, little Justin was being uncharacteristically quiet, so when the teacher prodded him about his father, he replied, "My father's an exotic dancer in a gay cabaret and takes off all his clothes to music in front of other men and they put money in his underwear. Sometimes, if the offer is really good, he will go home with some guy and stay with him all night for money."
The teacher, obviously shaken by this statement, hurriedly set the other children to work on some exercises and took little Justin aside.
"Is that really true about your father?"
"No," the boy said. "He works for the Democratic National Committee and helped to get Obama elected, but it's too embarrassing to say that in front of the other kids."
