A woman and her 12-year-old son were riding in a taxi in Detroit. It was raining, and all the prostitutes were standing under awnings.
“Mom,” said the boy, “what are all those women doing?”
“They’re waiting for their husbands to get off work,” she replied.
The taxi driver turns around and says, “Geez lady, why don’t you tell him the truth? They’re hookers, boy! They have sex with men for money.”
The little boy’s eyes get wide and he says, “Is that true Mom?”
His mother, glaring hard at the driver, answers “Yes.”
So the kid asks, “Mom, if those women have babies, what happens to them?”
She said, “They become taxi drivers.”
