The clip has story similar to Twisted Sister - We're not gonna take it. Sort of little guy is being yelled at for probably wasting his life. He then pushes a giant speaker to the living room, where his parents sit and peacefully watch TV. He puts on glasses, turns the volume to something like crazy and plays the guitar which sends his father flying high in the sky, through the roof.
That's the intro to the long version of Michael Jackson's "Black or White", much heralded at the time for its cutting edge use of computerized morphing technology. The "little guy" was actually Home Alone star Macaulay Culkin, and the dad was Cheers' favorite "Norm" (George Wendt).
Culkin and Jackson had a much publicized friendship that people started to feel a little icky about in later years when Jackson faced molestation accusations (not from Culkin).
