Two blondes are digging a ditch on a VERY hot day.

One turns to the other and says, "Just why are we down in this hole diggin' a ditch when our boss is standin' up there in the shade of a tree?"

"Er....I don't know," responds the other. "I'll go up and ask him."

So he climbs out of the hole and goes over to his boss.

"Hey, boss! Why are we diggin' in the hot sun and you're standin' in the shade?"

" 'Intelligence'," the boss says.

"Whadaya mean, 'intelligence'?"

The boss says, "Well, here let me show you. I'll put my hand on this tree and I want you to hit it with your fist as hard as you can. Okay?"

The blonde takes a mighty swing and tries very hard to hit the boss' hand. The boss, however, removes his hand and the blonde ends up hitting the tree.

The boss then says, "That's 'intelligence'!"

So, the blonde heads back down to his hole. His friend anxiously asks, "Well......what'd he say?"

"He says we're down here because of 'intelligence'."

"What? What's 'intelligence'?" says the friend.

The blonde puts his hand on his face and says....

"Take your shovel and hit my hand."
