So this Norwegian

[Daddles]

So this Norwegian applies for a job on a building site. Big bugger he was, too big for the liking of the foreman - scared he'd drink too much beer at the lunchtime **** up. So the foreman had a think and decided to ask some questions he knew the bloke couldn't answer.

"Here's your first question," says the foreman and takes a sip from his mug of tea. "Without using numbers, represent the number 9."

"Dat is easy," says the Norwegian, and drags a bit of paper towards him and draws three trees.

"What the hells that supposed to be?" says the foreman.

"De answer. Tree and tree and tree make nine," says the Norwegian.

"Fair enough," says the foreman scratching his bald spot. "Here is your second question. Use the same rules, but this time the number is 99."

The Norwegian stares into space for a bit, picks up the picture and makes a smudge on each tree. "Ere you go."

The foreman scratches his head again and says, "How on earth do you get that to represent 99?"

"Each of da trees is dirty now! So it's dirty tree, and dirty tree, and dirty tree. Dat is 99."

The foreman's getting worried - he can see the lunchtime jug getting emptied at a hell of a rate and none of it into his jar, so he says: "All right, last question. Same rules again, but this time, the number is 100."

The Norwegian stares into space some more, picks up the picture again and makes a little mark at the base of each tree, and says, "Ere you go. One hundred."

"You gotta be nuts if you think that represents a hundred!" says the foreman.

The Norwegian leans forward and points to the marks at the base of each tree, and says, "A little dog come along and crap by each tree. So now you got dirty tree and a , dirty tree and a , and dirty tree and a , which make one hundred. So when I start?"
