A young hotshot gets a job with the IRS. His first assignment is to audit an old rabbi.
He thinks he'll have a little fun with the old guy, 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 matzo crumbs from your table?"
We send them to the matzo ball factory, and every once in a while they send us a free box of matzos."
The kid grins and thinks he's got him on this one: "And what do you do with the foreskins from your circumcisions?"
The old rabbi smiles beatifically and replies:
We send them to the IRS, and every once in a while they send us a little prick like you."
