An old woman is going up in a lift in a very Iavish department store when a young, beautiful woman gets in, smelling of expensive scent. She turns to the old woman and says arrogantly "Romance by Ralph Lauren, £100 a bottle."
Then another young woman gets in the lift, She also turns to the old woman and says snootily "Chanel No 5, £150 a bottle."
A few floors later, the old woman has reached her destination. As she gets out, she looks both woman in the eye, then turns round, bends over and farts, saying "Broccoli, 25p a pound."
