A hospital was being audited by an agent from HM Revenue and Customs.
While the agent was checking the books, he turned to the executive of the hospital and said “I notice you buy a lot of bandages. What do you do with the end of the roll when there's too little left to be of any use?"
"Good question," noted the executive . "We save them up and send them back to the bandage company and every once in a while, they send us a free roll."
"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 plaster purchases? What do you do with what's left over after setting a cast on a patient?"
"Ah, yes," replied the executive, realising that the inspector was trying to trap him with an unanswerable question. "We save it and send it back to the manufacturer and every so often they send us a free bag of plaster."
"I see," replied the auditor, thinking hard about how he could fluster the know-it-all executive. "Well, What do you do with all the remains from the circumcision surgeries?"
"Here, too, we do not waste," answered the executive. "What we do is save all the little foreskins and send them to the tax office, and about once a year they send us a complete prick."
