The Tax Official in an unnamed country has come to a synagogue for an
inspection.
The Rabbi is accompanying him.
"So rabbi, tell me, please, after you have distributed all your
unleavened bread, what do you do with the crumbs?"
"Why, we gather them carefully and send them to the city and then they
make bread of them again and send it back to us."
"So what about candles after they are burnt? What do you do with the
ends?"
"We send them to the city as well, and they manufacture new candles from
them and send them to us."
"And what about circumcision? What do you do with those leftover
pieces?"
The rabbi, wearily replyed, "We send them to the city as well."
"To the city? And what do they send to you?"
"Today they have sent you to us."
