3. VANILLA ICE AS HIMSELF IN TEENAGE MUTANT NINJA TURTLES II: THE SECRET OF THE OOZE (1991)

We find it hard to believe that the filmmakers behind Teenage Mutant Ninja Turtles II ever thought it would be a good idea to include Vanilla Ice in this movie. Hell, his career was basically over before the movie got released on home video. But some Hollywood bigwig must have thought featuring a flash-in-the-pan novelty act would somehow line his pockets with more cash when all was said and done.

In this short cameo, Ice took a movie that was decent, at best, and turned it into an example of everything that was awful about the '90s. He sings, he dances, he horrifies. It’s a pretty telling sign that in a scene involving five man-sized turtles and a talking coyote that Vanilla Ice is still the most ridiculous looking thing in the building.
