More chance of Santa's sled receiving an RCA than anybody at Fort Fumble actually being held accountable for anything...
This is a favourite.
Santa has had CASA in, they've checked the paperwork, recency, load sheets, etc and are walking out to the sleigh for the check flight. Santa notices the examiner is carrying a shotgun and asks what for. The examiner says " Santa, I really shouldn't tell you this but you're going to lose an engine shortly after take-off"
Boom-boom!!
