here's one I just got by email: (sorry it's kinda long)
A construction Boss in Boston was interviewing men when
along came a guy named Vinny from New York. I'm not hiring
any wise-ass New Yorker, the foreman thought, so he made
up a test hoping that Vinny wouldn't be able to answer the
questions, and he'd be able to refuse him the job without
getting into a dispute.
"Here's your first question," the foreman said. "Without
using numbers, represent the number 9."
"Widout numbiz?" Vinny says. "Dat's easy," and he proceeds
to draw 3 trees.
"What's this?" the boss asks.
The New Yorker Vinny replies, "Ain't you got no :censor::censor::censor::censor:'in brains?
Tree 'n Tree 'n Tree makes nine. Faghedaboutit......"
"Fair enough," says the Boss. "Here's your second question.
Use the same rules, but this time use the number 99."
Vinny stares into space for a minute, then picks up the
picture he has drawn and makes a smudge on each tree.
"Dare ya go, Buddy."
The Boss scratches his head and says,
"How on earth do you get that to represent 99?"
Vinny says "Each a da tree's is 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 Vinny
from New York, so he says, "All right, last question. Same
rules but this time use 100."
Vinny stares into space again, then picks up the picture once
again, makes a little mark at the base of each tree and says,
"Dare ya go, Mac, a hunnert."
The Boss looks at the picture for a moment and says, "You must
be nuts if you think that represents 100!"
Vinny leans forward and points to the marks at the base of the
trees. "A little doggie comes along and takes a poop on each a
dem trees, so now ya got dirty tree an' a turd, dirty tree an'
a turd, dirty tree an' a turd - which makes one hundred.
Bada boom , bada bing. When do I freakin' start?"
