Tax inpector visits a synagogue

Tax inspector visits a synagogue to pursue an inquiry (yes, I know, I wouldn’t have allowed that either!). During the meeting, thinking he may have found an undeclared benefit-in-kind, he asks the rabbi what he does with the wax that falls from the candles.
"Well," says the rabbi, "I collect all the left-over wax and send it to the candle-maker. After a while, he sends me a complete candle."
Foiled by this explanation, the inspector tries to find something else. After a while he asks the rabbi what he does with the crumbs from the biscuits used in the ceremonies.
"Well," says the rabbi, patiently, "I collect all the left-over crumbs and send them to the biscuit-maker. After a while, he sends me a complete biscuit."
The inspector is frustrated, once again. After some more thought, he asks the rabbi what he does with the foreskins that are removed during the circumcisions.
"Well," says the rabbi, "I collect all the foreskins and send them to the local tax office. After a while they send me a complete dick." 😆
