A woman and her ten-year-old son were riding in a cab in New York City.
It was raining and all the hookers were standing under the awnings.
"Mom," said the boy, "what are all those women doing?"
"They're waiting for their husbands to get off work," she replied.
The cabbie 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?"
The woman gets very angry but she keeps quiet.
After a few minutes, the kid asks, "Mom, what happens to the babies those women have?"
"Most of them become cab drivers," she said.
