A mother and daughter were riding in a cab though New York City when the
daughter noticed some scantily clad women loitering on a street corner. "Mommy,"
the little girl asked, "what are all those ladies doing?"
"They're waiting for their husbands to come home from work." the mother
answered.
"C'mon lady, they're hookers!" retorted the cab driver.
After a stunned silence, the daughter asked, "Mommy, do hookers have
children?"
"Of course," the mother replied, "where do you think cabbies come
from?"
