Norwegian Math

>  A Norwegian man wants a job, but the foreman
>  won't hire him until he passes a little math test.
>
>  "Here's your first question," the foreman said.
>  "Without using numbers, represent the number 9."
>
>  "Without numbers?" the Norwegian says, "Dat is
>  easy."   And he proceeds to draw three trees.
>
>  "What's this?" the boss asks.
>
>  "Ave you got no brain?  Tree and tree and tree
>  make nine," says the Norwegian.
>
>  "Fair enough," says the boss.  "Here's your second
>  question.  Use the same rules, but this time the
>  number is 99."
>
>  The Norwegian stares into space for a while, then
>  picks up the picture that he has just drawn and
>  makes a smudge on each tree.    "Ere you go."
>
>  The boss scratches his head 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 boss is getting worried that he's going to
>  actually have to hire this Norwegian, so he says,
>  "All right, last question.  Same rules again, but
>  represent the number 100."
>
>  The Norwegian stares into space some more,
>  then he picks up the picture again and makes a
>  little mark at the base of each tree and  says,
>  "Ere you go.  One hundred."
>
>  The boss looks at the attempt.  "You must be
>  nuts if you think that represents a hundred!"
>
>  (You're going to love this one!!!)
>
>  The Norwegian leans forward and points to the
>  marks at the base of each tree and says, "A little
>  dog came along and crap by each tree. So now
>  you got dirty tree and a turd, dirty tree and a turd,
>  and dirty tree and a turd, dat make one hundred.
>  So, when I start?"
