Freaked is a 1993 American comedy film directed by Tom Stern and Alex Winter

Originally conceived as a low-budget horror film featuring the band Butthole Surfers, Freaked went through a number of rewrites, eventually developing into a black comedy

Great physical effects, slapstick nonsense, and a lot of genuinely funny scenes. Spot the uncredited Keanu Reeves cameo
