An elderly gentleman who is less potent than he was in his youth consults his doctor, who after trying many unsuccessful remedies refers him to an African Witch Doctor.
Saying 'I can cure this', the Witch Doctor throws a white powder into a flame, and there is a flash followed by billowing blue smoke. ‘This is powerful healing, but you can only use it once a year’, the African explains. ‘All you have to do is say '123,' and it shall rise for as long as you wish!'
The patient asks, 'What happens when it's over, and I don't want to continue?' The Witch Doctor replies, 'When your partner can take no more sex and is completely satisfied, all she has to say is '1234', and it will then go down. But be warned, your potency will not return again for another year…'
The old gent rushes home, anxious to try out his new powers. That night he showers, shaves, and smothers himself in expensive perfumes. He slides into bed, cuddles up to his wife, says '123', and suddenly he has the most gigantic erection, just as the Witch Doctor promised. His wife turns over and asks, 'What did you say '123' for?'
The Beadle and Mrs Malaprop have asked Ben to confirm that this tale bears no relation to any denizens of the Burrow.
