good one

[Big N' Blue]

A mother, accompanied by her small daughter, were in New York City. The mother was trying to hail a cab, when her daughter noticed several wildly dressed women who were loitering on a nearby street corner.

The mother finally hailed her cab and they both climbed in, at which point the daughter asks her mother, "Mommy, what are all those ladies waiting for by that corner?", to which the mother replies, "Those ladies are waiting for their husbands to come home from work."
The cabbie, upon hearing this exchange, turns to the mother and says, "Ahhhhhhh, C'mon lady!!!! Tell your daughter the truth!!!! For crying out loud. They're hookers!"
A brief period of silence follows, and the daughter then asks, "Mommy, do the hooker ladies have any children?" The mother replies, "Of course dear. Where do you think cabbies come from?"
