A mother and her young son were riding in a taxi through the rougher part of town, when the little boy noticed several streetwalkers patrolling their beat and he asked who they were.
The mother explained, ?Those are ladies whose husbands work on the docks, and they?re waiting to walk their husbands home from work.?
The cab-driver, who had been listening, looked back over his shoulder and guffawed, ?Lady, those are just plain old hookers. Why don?t you tell the kid the truth??
Everything was quiet for a while, then the boy asked his mother, ?Do hookers have little boys too??
She answered sweetly, ?Of couse they do, dear. That?s where all the taxi drivers come from.?
