Expensive Perfume

A young, beautiful woman gets into the elevator, smelling like expensive perfume. She turns to an old woman and says arrogantly, "Giorgio Beverly Hills, 0 an ounce!"
Another young, beautiful woman gets onto the elevator and also smells of very expensive perfume. She arrogantly turns to the old woman and says, "Chanel No. 5, 0 dollars an ounce!"
About three floors later, the old woman has reached her destination and is about to get off the elevator. Before she leaves, she looks both of the women in the eyes, turns around, bends over, farts and says, "Broccoli, 49 cents a pound!"
