Sometimes I wonder who has time on their hands to find clips and edit them into such things, but then I remember the kinds of things I did when I was 14-15. Granted, the internet was much younger then, but I spent hours upon hours building fan pages for Gummi Bears, Labyrinth, and other popular culture topics I can't even remember anymore. Of course, this was all on one of those AOL Hometown pages that bit the dust back in 2008, but, alongside SimTower, it was what I did for fun, backed up on 3.5" disks.
Digression aside, Jim Cliff has posted a video on YouTube with 60+ clips of 80s television shows spliced together to make out the lyrics to Frozen's "Let it Go." (a song which will, apparently, never actually go away.) It's done pretty well, and I laughed at multiple points, so thought you might get a kick out of it, too.
