An Englishman, a Scots man, and an Irish man are sentenced to 100...

An Englishman, a Scots man, and an Irish man are sentenced to 100 lashes.

The judge was in a benevolent mood though and offered them each a request that maybe would make it easier on them.

The Scottish man asked for a pillow to be strapped to his back, but it had worn away after 50 lashes and he suffered for the remaining 50.

The Englishman being smart asked for 2 pillows, and he didn't feel any of the lashes on his back.

Before the Irishman was asked, the judge said "I love Ireland, it has given us the greatest music, poets, writers and art - because of this you get 2 requests"

The Irishman thought and said "firstly I'd like 200 lashes, and second of all strap the Englishman to my back"
