The Internal Revenue sent their auditor (a nasty little man) to audit a synagogue.
The auditor does all his checks, and then turns to the Rabbi and says: "I noticed that you buy a lot of candles."
"Yes," answered the Rabbi.
"Well, Rabbi, what do you do with the candle drippings?" he asked.
"A good question," noted the Rabbi. We actually save them up. When we have enough, we send them back to the candle maker. Every now and then, they send us a free box of candles."
"Oh," replied the auditor somewhat disappointed that his question actually had a practical answer. So he thought he'd try another question, in his obnoxious way . . .
"Rabbi, what about all these matzo purchases? What do you do with the crumbs from the matzo?"
"Ah, yes," replied the Rabbi calmly, "we actually collect up the crumbs. We send them in a box back to the manufacturer and every now and then, they send us a box of matzo balls."
"Oh," replied the auditor, thinking hard how to fluster the Rabbi.
"Well Rabbi," he went on, "What do you do with all the foreskins from the circumcisions?"
"Yes, here too, we do not waste," answered the Rabbi. What we do is, we save up all the foreskins and when we have enough, we actually send them to the Internal Revenue Service."
"Internal Revenue Service?," questioned the auditor in disbelief.
"Ah, yes," replied the Rabbi, the "Internal Revenue Service. And about once a year, they send us a little prick like you."
