It is a little known fact that even Santa must keep his pilot's license current in order to make his deliveries every year. And so, the old man wasn't too surprised when he got a letter from the FAA informing him that an examiner would be appearing shortly to run him through the usual re-certification drill.
Santa immediately dispatched a detail of elves to wash and polish the sleigh, another group was assigned to inspect, service, and repair all the tack, and a third squad started curry-combing the reindeer. Santa himself got out his logbook and paperwork, making sure everything was in order.
On the appointed day, the examiner arrived. After the ritual cup of coffee, he reviewed Santa's logbook, then after a meticulous review of Santa's weight and balance calculations, accompanied Santa outside. The examiner watched as Santa conducted his pre-flight, closely looking at everything from the bells on the back of the sleigh to Rudolph's red nose. When he was finished, he turned to Santa and said: "It looks pretty good so far. Let me go get one thing out of my truck, and then we'll take her up."
When the examiner returned, Santa was already belted into the sleigh and ready to taxi. As the examiner climbed into the sleigh, Santa noticed that he was carrying a shotgun. "What's that for?" Santa asked.
The examiner looked at him, then winked: "I'm not really supposed to tell you this, but you're going to lose an engine on takeoff."
He who fights with monsters might take care lest he thereby become a monster.
