"There were three men, an Irishman, an Englishman
and a Welshman, and they all climbed up to the 
top of a cliff. At the top they met a man, and 
the man said "If you can take your watch and drop
it down the cliff, catch it again and bring it 
back up I will give you $500." 

The Welshman thought he could do it, so he 
dropped his watch and ran all the way down to the
bottom of the cliff, and he came back up with his
watch in pieces. 

The Irishman thought he could do it as 
well, so he dropped his watch and jumped down 
the cliff and came back with his watch intact, 
but he was on a stretcher. 

The Englishman thought he could do it as well,
so he dropped his watch and walked slowly down
the cliff, and he came back up with his watch 
working. 

The man said, "How in the world did you do that?"
"I set my watch back two hours," said the 
Englishman.
