1. Teenage Mutant Ninja Turtles (syndication, 1987-1990; CBS, 1987-1996)
If you were trying to build the perfect franchise for guys of all ages, you couldn't do any better than TMNT: four skateboarding turtles living in a sewer with their grizzled rat sensei, munching on pizza and banging the hot TV reporter from Channel 6 (OK, so maybe that last one's just implied).
Oh, and the best part? They're fucking ninjas for fuck's sake. Yes, the whole enterprise got a little overplayed once it entered the realm of lunch boxes and plush toys, but there was a time when Saturday mornings weren't shit without the turtles with the Renaissance names. And to think all the kids these days get is a cheesy CGI flick.
Cowabunga to our youth!
