A man walks into the doctor's. 'Doctor, can you help me?' he says, 'My penis has holes all up and down it. When I go to the toilet it sprays out in all directions.' The doctor examines the organ and hands him a card with a name and address on it. 'Is this the name of a specialist?' asks the man. 'No,' says the doctor. 'He's a clarinet tutor. He'll teach you how to hold it.'
