Just when that Mariah Carey/Jimmy Fallon collaboration was starting to make us feel warm-hearted about holiday music, along comes a new music video starring Olivia Newton-John and John Travolta to put a big lump of “Wha?!?!” in our stockings.

As previously established, Travolta and Newton-John — stars of the beloved musical “Grease” and the barely remembered “Two of a Kind” — teamed up to make a Christmas CD this year. As also previously established, the cover of that CD (see above) is the worst.

And as established today on the Internet, the music video for one of the songs on said release — the twangified “I Think You Might Like It” — might be even more disturbing than the album art.

There isn’t much to say about this video that hasn’t already been said by Vulture’s list called “Ten Things That Creep Us Out About John Travolta and Olivia Newton-John’s New ‘Music Video.’ ”

However, I would like to formally register my confusion about the basic narrative structure of this video. Translation: I don’t understand why Travolta picks up Newton-John after landing his private jet and acts all lovey-dovey with her when his wife, Kelly Preston, and their children are dancing around at an airport. It doesn’t make sense.

Anyway, watch the thing, then immediately fire up a clip of “You’re the One That I Want” to wash out your brain and refill it with more pleasant images of Travolta and ONJ.
