A woman and her ten year old son were riding in a taxi. It was raining and all the prostitutes were standing at the bus stop.
Boy: Mom, what're those women doing?
Mom: They're waiting for their husbands to get off work.
Taxi driver: Lady, why don't you tell him the truth. They're hookers, boy. They have sex with men for money.
Boy: Is that true, mom?
His mother, glaring hard at the driver, answers, "Yes."
After a few minutes, the kid asks: Mom, what happens to the babies those women have?
Mom: They become taxi drivers!
