I was always convinced most of those horrible karaoke video tracks were either B-roll/"plot" from low budget porn or a clever way to write off your vacation home movies as a business expense shooting stock video.
Hell, this is more coherent than most karaoke vids, actually.
Pioneer Laser Karaoke discs are one of my favorite things. I used to have a bunch of them but then my player broke and I left them at a friend's house and then moved away.
Thanks to laser karaoke I had the life experience of seeing a tiny, gay Italian man putting his testicles on a large, topless woman's ear while I sang "Like a Virgin."
I was drunk on cinco de mayo years ago randomly at some bar in South Milwaukee and sang "proud to be an American" Shatner style, backwards chair, cigarette and all. We were four hipsters in an otherwise straight-up NASCAR bar, and I was convinced halfway through that I was going to either get tossed or get my ass kicked. Instead they all cheered. Maybe they thought I was tone deaf
