Once I was flying into London Gatwick around Christmas time. I'd goofed when making travel plans, bc Heathrow would have been closer to my UK destination. However, the scanners at Heathrow were going mad over Christmas pudding, and the sensors thought the dense cakes were plastique, or some such. Turned out it was faster getting in and out of Gatwick.
Speaking of Christmas pudding, here's a guy who sculpted a couple shrubs into a giant Christmas pudding. Yeah, it's silly, but it's kind of cute!
