Expensive perfume

A young and beautiful woman gets into the elevator, smelling like expensive perfume.
She turns to the old Italian woman on the elevator with her and says arrogantly, "Giorgio - Beverly Hills, $100 an ounce!"
Another young and beautiful woman gets on the elevator and also smells of very expensive perfume. She arrogantly turns to the old Italian woman and says, "Chanel No. 5, $150 an ounce!"
About three floors later, the old Italian woman has reached her destination and is about to get off the elevator. Before she leaves, looks both beautiful women in the eye, turns, bends over, and farts. "Broccoli - 49 cents a pound."
