An old woman is going up in a lift in a very lavish department store when a beautiful young woman smelling of expensive scent gets in. 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 too turns to the old woman and says snootily, 'Chanel No 5, £150 a bottle.'

A few floors up the old woman reachs her destination. As she leaves she cuts a loud, stinky fart and says, 'Broccoli, 25p a pound.'
