A construction site boss was interviewing men for a job, when along
came plenderj (but we'll call him Murphy). The boss thought "I'm not hiring that lazy Irishman,"
so he decided to set a test for Murphy, hoping he wouldn't be able
to answer the questions, and he'd be able to refuse him the job
without getting into an argument.
The first question was, "Without using numbers, represent the number
nine".

So Murphy says, "Dat's easy" and proceeds to draw three tree's.

The boss says,"What the hell is that?"

Murphy says "Tree 'n tree 'n tree makes nine".

"Fair enough", says the boss. "Second question, same rules, but
represent 99".

Murphy stares into space for a while, then makes a smudge on each
tree. "Der ya go sir" he says.

The boss scratches his head and says, "How on earth do you get that
to represent 99".

Murphy says "Each tree's dirty now! So it's dirty tree, 'n dirty
tree 'n dirty tree, dat's 99".

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

Murphy stares into space again, then he shouts, "Got it!"

He makes a little mark at the base of each tree, and says 'There ya
go sir 100."

The boss looks at Murphy's attempt and thinks, "Ha! got him this
time." He said "Murphy, you must be mad if you think that represents
a hundred".

Murphy 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
you've got, dirty tree an' a turd, dirty tree 'n a turd, an' dirty
tree 'n a turd, which makes one hundred. When do I start me job"?
