Quick Christmas Joke.

Just before Christmas, Santa Claus gets a surprise visit from the Federal Aviation Administration. The examiner walks slowly around the sled, looking at each of the reindeer harnesses, the runners, and the sled's body. Then he weighs Santa and performs balance calculations to determines the sled's payload.
'Ok, everything checks out,' he says while stepping into the sleigh. 'But you've still got to pass the flight-test.'

Saint Nick jumps in, then notices the FAA examiner has a shotgun sitting across his lap.

'What's that for?' gulps Santa.

'Technically, I'm not supposed to tell you this,' winks the examiner, 'but you're going to lose an engine on take-off.'
