Pat and Mick have just started their job installing telephone poles. At the end of the first week they both go to collect their wages and the boss tells Mick he is dismissed.

“Why?” asks Mick, thinking he’d worked hard and done an excellent job.

“Well,” said the boss. “Pat has put in 50 poles this week and you have only done 5.”

Mick looks rather perplexed and angry.  “But look how far he has left them sticking out!”
