Taylor Swift's smash single "Shake It Off" has become so ubiquitous since its release earlier this fall that it somehow even managed to travel through time.
How else do you explain her album sales, which look like totals from a bygone era, or the fact that an '80s aerobics routine managed to use the hit track?
Or so you might think, thanks to YouTube user Thomas Jung, who combined this '80s video with the song, making for just about the best video maybe ever:
The choreography, originally performed at the 1988 Crystal Light National Aerobic Championship hosted by Alan Thicke, syncs perfectly to "Shake It Off."
We're not sure what's funnier, how well Swift's song fits the video or the fact that this was, at one point, an actual thing that existed somewhere in civilization.
It's almost as if Swift (who was born in 1989 and whose already wildly successful album 1989 was released last week) wrote the tune while watching this clip.
We can certainly see her dancing like this in the studio or at home.
