An Italian workman wants a job, but the foreman asks him to pass a math test first. "First question", the foreman says, "without using numbers, represent the number 9". "Withouta numbers?" the Italian says. "Datsa easy." And he proceeds to draw three trees. "What's this?" the foreman asks. "Ave you gota no brain? Tree and tree and tree makea nine," says the Italian. "Fair enought", say the foreman. "Next question, use the same rule, but this time the number is 99." The Italian stares into space for a while, then picks up the picture that he just drew 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?" "Eacha of da trees is a dirty now. So, it's dirty tree, and dirty tree, and dirty tree. Datsa a 99." The boss is getting worried that he's going to actually have to hire the Italian, so he says, "All right, last question. Same rules again, but represent 100." The Italian 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 and says, "You must be nuts if you think that represents a hundred." The Italian leans forward and says, "A little doga come along and ****a by eacha tree. So now you gota dirty tree and a turd, dirty tree and a turd, and a dirty tree and a turd. Data makes one hundred. So, whenna I start?"
