On a AA flight ORD-MCI on Christmas Day about 7 years ago, the entire safety briefing was read like 'Twas the night before Christmas. Very well done and got a round of applause. Unfortunately, there was very heavy ground fog at MCI and we ran low on juice circling so we had to divert to DSM. We didn't get off the plane but of course they still had to do another safety briefing, which was the regular script.
It was rather weird on approach to MCI seeing radio towers (and nothing else) sticking out of the fog, which hugged the ground. It's one thing to see the TV tower at Twin Peaks in San Francisco coming through the fog, but you know it's pretty flat in Missouri.
Fortunately my sister held Christmas dinner for me.
