There were these three guys, a Irishman, an Italian guy and a Jewish guy.
They all worked together at a factory.
Every day they noticed that their boss leaves work a little early. So one
day they meet together and say that today when the boss leaves, they'll all
leave early too.
The boss left and so did they.
The Jewish guy goes home and goes to rest so he can get an early start.
The Italian guy goes home and cooks dinner.
The Irishman goes home and walks to his bedroom. He opens the door slowly
and sees his wife in bed with his boss so he shuts the door and leaves.
The next day the Italian and Jewish guys are talking and plan to go home
early again. They ask the Irishman if he wants to leave early again and he
says, "No."
They ask him why not and he said, "Because yesterday I almost got caught!"
