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 perfume. She turns to the old woman and says arrogantly: 'Romance by Ralph Lauren, Â£100 a bottle.' Then another young woman gets in the lift, She also turns to the old woman and says snootily, 'Chanel No 5, Â£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: 'Brussel sprouts, 25p a pound.'
