A woman and her son were takin...

A woman and her son were taking a cab in New York City. It was raining and all the hookers were standing under the awnings.
"Mommy," said the little boy, "what are all those ladies doing?"
"They're waiting for their husbands to get off of work," she replied.
The cabbie turns around and says, "Geez lady, why don't you tell him the truth? They're hookers. They have sex with men for money."
The little boy's eyes get wide and he says, "Is that true, mommy?" His mother, glaring at the cabbie, answers in the affirmative.
After a few minutes, the kid asks, "Mommy what happens to the babies those ladies have?"
"They mostly become cab drivers," she replied.
