"Jingle Bells" is not a Christmas song. It's a Winter Jam written in in a bar in Medford, Massachusetts, not far from wher I have lived all my life, in 1857. It's about drinking and driving and picking up girls, in an innocent, 19th century New England kind of way (not kidding). You know, a party song.
I bet these two drank that whole bowl of punch between them in an hour, then took the Cadillac out for a spin. Probably left the car in a ditch and wound up in a casino. Same idea.
