Many years ago a little Irish farmer won the football pools and decided to see the sights of London.
In Holyhead he found himself in a train compartment alone with a bowler hatted Englishman.
The Irishman explained how he had never left Ireland before and what had happened to him.
The Englishman said (in suitable posh accent), "Well my good man, to while away these interminable train journeys, I like to play a simple little game. It goes like this; you ask me a question and if I can't answer it I give you a pound.
And then I ask you a question and if you can't answer it, you give me a pound, and so on"
The Irishman thought about this and said, "It sounds quite fun but I am but a simple farmer, with little experience of the world, and you are obviously an educated and well travelled man.
Do you not think it would be fairer if I couldn't answer your question that I should only have to give you half?"
The Englishman considered this for a moment and said, " Yes I can see that, I did go to Eton and Oxford, it sounds fair enough to me".
"Right" said the little Farmer "I'll kick off with one"
"What has has seventy five legs on the underside and ninety five legs on the overside?"
The Englishman was nonplussed, and the stations passed by, Crewe, Birmingham, he racked his brains and started to lightly perspire!
As they drew quite near to London he pulled out his wallet and gave the a pound to the Irishman said,"Well my good man, you really have me there, here's a pound.
Now tell me the answer?"
The Irishman looked at him with a twinkle, took the pound and said "Well I don't know either, Sir"
And gave him fifty pence!
