I couldn't find the joke page. So here it is anyways. 
 
 
 At the end of the tax year the Tax Office sent an inspector to audit the 
books of a synagogue. 
While he was checking the books he turned to the Rabbi and said, "I 
notice you buy a lot of candles. What do you do with the candle 
drippings?" 
"Good question," noted the Rabbi. "We save them up and send them back to 
the candle makers, and every now and then they send us a free box of 
candles." 
"Oh," replied the auditor, somewhat disappointed that his unusual 
question had a practical answer. 
But on he went, in his obnoxious way: "What about all these matzo 
purchases? What do you do with the crumbs?" 
"Ah, yes," replied the Rabbi, realising that the inspector was trying to 
trap him with an unanswerable question. "We collect them and send them 
back to the manufacturers, and every now and then they send a free box 
of matzos." 
"I see," replied the auditor, thinking hard about how he could fluster 
the know-it-all Rabbi. 
"Well, Rabbi," he went on, "what do you do with all the leftover 
foreskins from the circumcisions you perform?" 
"Here, too, we do not waste," answered the Rabbi. "What we do is save up 
all the foreskins and send them to the Tax Office, and about once a year 
they send us a complete dick like you."
