While checking the books, he turned to the rabbi and asked, "I notice you buy a lot of candles, what do you do with the candle drippings?"
"Good question," retorted the rabbi, "we save them up and send them to candle makers, every now and then they send us a free box of candles."
The inspector was a bit disappointed that his unusual question had a practical answer.
But he continued, in his obnoxious way,"What about all these biscuit purchases? What do you do with the crumbs? "
"Ah! Yes." replied the rabbi realizing that the inspector was trying to trap him with an unanswerable question. "We collect them and send them back to the manufacturers, every now and then they send us a free box of biscuits."
The auditor thought hard about how he could fluster the know-it-all rabbi. "Well rabbi, what do you do with all the leftover foreskins from the circumcisions you perform?"
"Here, too, we do not waste", said the rabbi. "What we do is save up all the foreskins and send them to the Tax Office, and once a year they send us a complete dick like you."
