I appreciate sophisticated humor. The ONLY thing that remotely saved it is the fact that it was a reference to a semi obscure cult classic and the ironical fact that these clean cut all American types were singing a goofy Christmas song.
The reference allows people to look at it and go, "Oh, I know that movie and recognize those lines. And I liked that movie. Therefore I think this is a funny video."
But, I hold no grudge against anybody else that finds it humorous. I will grudgingly give it a "cute" rating if that will make you feel better.
Regardless of my love for Patrick Swayze, I do think it was the seriousness and formality of the chorus that made it laughable.
So I think that is close to what you’re saying.
