One evening a Parisian grandmother collects her visiting English granddaughter in a taxi at Orly Airport.
Leaving the airport they pass several whores in small groups, some with little poodles in their arms.
"What are those ladies doing, Grandmere?"
"Cherie, those ladies have been to a bridge club and a dog show and are waiting for a lift home"
The driver laughs and sneeringly says "Madame, don't mislead the girl, she needs to know the facts of life, Mam'selle, they are prostitutes, waiting to have sex with strangers for money!!"
"Oh!" exclaims the girl, "and, if they get pregnant, what will happen to the little babies? "
Says grandma "Pah! Don't worry, ma petite, the world will always want more taxi-drivers..."
