Canadians do have a sense of humor!...
A young hotshot gets a job with the Revenue Canada. His first
assignment is to audit an old rabbi. He thinks he'll have a little
fun with the old rabbi , so he says, "Rabbi, what do you do with the
drippings from the candles?"
The rabbi says, "We send them to the candle factory, and every once in a while they send
us a free candle."
The kid says, "And what do you do with the crumbs from your
table?"
The rabbi says, "We send them to the matzoh ball factory, and
every once in a while they send us a free box of matzoh
balls."
The kid says, "And what do you do with the foreskins from your circumcisions?"
The rabbi says, "We send them to Revenue Canada, and every once in a while they send us a little prick like you."
