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 turned around and said, "Geez, lady, why don't you tell the kid the truth? They're hookers, boy! They have sex with men for money."

The little boy's eyes got wide and he asked, "Is that true, Mom?"

His mother, glaring hard at the driver, answered,"Yes."

After a few minutes the kid asked, "Mom, if those women have babies, what happens to them?"

She replied, "Most of them become taxi drivers."

Now that's funny!
