The melody comes from The Final Countdown, the 1986 hit by Swedish rock band Europe, whose keyboard riff became a staple for dramatic entrances and sports moments.

The contrast spread in meme edits and short videos because the tune is known worldwide, so even a few notes set up an expectation that the drooping ending instantly undercuts for comic effect.
