A London lawyer and a Lancashireman are sitting next to each other on a long flight up North.
The lawyer is thinking that Northerners are all 'cloth cap and clogs' and that he can fool them easily
So the lawyer asks if the Lancashireman would like to play a fun game?
The Lancashireman is tired and just wants to take a nap, so he politely declines and tries to catch a few ZZZs.
The lawyer persists and says that the game is a lot of fun. 'I ask you a question, and if you don't know the answer, you pay me only £5; you ask me one, and if I don't know the answer, I will pay you £500.'
This catches the Lancashiremans attention and to keep the lawyer quiet, he agrees to play the game.
The lawyer asks the first question. 'What's the distance from The Earth to the moon?'
The Lancashireman doesn't say a word, reaches in his pocket, pulls out a five-pound note, and hands it to the lawyer.
Now, it's the Lancashiremans turn. He asks the lawyer, 'What goes up a hill with three legs, and comes down with four?'
The lawyer uses his laptop, searches all the references he knows. He uses the air-phone; he searches the Net and even the British Library. He sends e-mails to all the smart Southern friends he knows, all to no avail. After over an hour of searching, he finally gives up. He wakes up the Lancashireman and hands him £500.
The Lancashireman pockets the £500 and goes straight back to sleep.
The lawyer is going crazy not knowing the answer. He wakes the Lancashireman up and asks, 'Well! What goes up a hill with three legs and comes down with four?
The Lancashireman reaches in his pocket, hands the lawyer £5 and goes back to sleep.
