Two Italian construction workers were in the field on an extremely hot day. The one says to the other, "hey how come we do all a da work and he gets all a da money?" pointing to the supervisor.
The other says, "I don't know, go ask him."
So Guido goes up to the supervisor and says "Hey, how come we do all a da work and you get all a da money?"
The supervisor says "Intelligence."
"What is this intelligence?" asks Guido
The supervisor puts his hand on a tree and says "Hita my hand as hard as you can!"
Guido winds up and with all his might and tries to hit the supervisor's hand. Just as he almost does the supervisor pulls his hand away and Guido hits the tree!
The supervisor says, "That's intelligence."
Still smarting Guido goes back to his coworker and his coworker says, "Hey what did he say?"
With a sheepish look on his face Guido puts his hand on his face and says "hita my hand as hard as you can."
