Ultimate Insult...!!!

A woman & her son were riding in a taxi.
All the prostitutes were standing at a bus stop.

Boy: Mom, what are these women doing here?
Mom: They are waiting for their husband.

Taxi driver: Why don't you tell him the truth, that they are hookers & have sex with men for money.

Boy: Is that true Mom?
Mom: (Glaring hard at the driver) says, YES.

Kid asks: Mom, what happens to the babies these women have?
