Boogers are a natural human occurrence, but The Ren & Stimpy Show decided to obnoxiously rub it in our face. In season one's "Nurse Stimpy" episode, Stimpy goes off to play with his "magic nose goblins." We quickly find out these are actually boogers that he wiped underneath a table. Yuck!
Being the disgusting person he is, Ren doesn't enjoy proper dental hygiene. In season two's "Ren's Toothache," we get up close and personal inside his filthy toothless mouth. This is a very good (and gag-inducing) reminder to ALWAYS brush your teeth. Just don't watch this episode while you're eating dinner.
This one is just a form of sick, sick humor. The creators thought it was a good idea to have a random jester grate his skin clean off with a cheese grater. To top it all off, he rubs the fresh wound with lemon juice. Umm, why was this considered a children's show again?!
This borderline-NSFW moment didn't appear on Nickelodeon, but on the spinoff Ren & Stimpy "Adult Party Cartoon". The original show was nauseating enough, but they decided to up the explicit level with the new series. This infamous scene shows Ren trying to "saw" a piece of wood on Stimpy's back. The sexual groans, sighs and sweats are incredibly inappropriate. No wonder it only lasted for three episodes on Spike TV!
