A Houston construction boss was interviewing men for a job, when along came a Louisiana Cajun. "You gotta pass my test first", he told the applicant.
"Here's your first question."
"Without using numbers represent the number 9."
"Without numbers?" the Cajun says. "Dat's easy," and proceeds to draw 3 trees.
"What's this?" the foreman asks.
"Well, tree and tree and tree make nine," says the Cajun.
"Fair enough," replies the foreman. "Here is your second question. Use the same rules, but this time the number is 99."
Cajun stares into space for a while, then picks up the picture of the
three trees 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?"
