A little English guy was in a pub in Ireland, and the huge barman challenged him to squeeze any more from a lemon than he could.
Only when told it was for charity did he give in.
So, big Paud cut a lemon in half and squeezed, then handed over the two wizened halves to the man.
To everyone's astonishment - it had never been done before - a few drops emerged from each half.
"God, man, what do you do for a living" asked one of the crowd, and the little guy answered, "oh, I'm a tax inspector".
