"Cajun Math" joke

A construction site boss was interviewing men for a job, when along came Boudreaux. The boss thought to himself, "I'm not hiring that ole lazy cajun..."

He decided to set a test for Boudreaux, hoping he wouldn't be able to answer the questions, and he'd be able to refuse him the job without any problems.

The first question the boss asked was, "Without using numbers, represent the number 9." Boudreaux says, "Dat's easy," and draws three oak trees. The boss says, "What the hell's that?" Boudreaux says, "Tree' n' tree' n' tree makes nine."

The boss says, "Fair enough." "Second question, same rules, but this time represent 99."

Boudreaux stares into space for a while, then makes a smudge on each tree. "Dere ya go, sir," he says. The boss scratches his head and asks, "How on earth do you get that to represent 99?" Boudreaux says, "Each tree is dirty now! so it's dirty tree,' n' dirty tree,' n' dirty tree...dat's 99!"

The boss, now is getting worried he's going to have to hire him, so he says, "All right, question three. Same rules once again, but this time represent the number 100."

Boudreaux stares into space again, then shouts, "I got it!" He then makes a little mark at the base of each tree, and says "Dere ya go, sir. 100." The boss looks at Boudreaux's attempt and thinking that he's got him this time.

"Go on Boudreaux, you must be crazy if you think that represents a hundred." Boudreaux leans forward and points to the marks at the tree bases, and says, "A little dog comes along and craps by each tree, so now ya got, dirty tree an' a turd, dirty tree an' a turd, an dirty tree an' a turd, which makes a hundred! So when can I start workin'?
