Censorship is supposed to protect viewers from being exposed to things like nudity, gore, explicit language and disturbing situations, basically all the things viewers usually want in movies or TV shows.
That's why creators are constantly battling the censors to keep their shows intact, censor despised content and all, and their struggle sometimes forces creators to flat out lie about what's happening on the screen.
Censors hate blood, and they actively force filmmakers to remove any trace of blood from their trailers, but back in 1980 Stanley Kubrick got away with telling the censors that his iconic blood flood in The Shining was really just "rusty water".
Because of Kubrick's lie the trailer, complete with that disturbing shot of the "rusty water" flooding towards the camera, briefly made it to theaters before being pulled by the MPAA.
Are you wondering why Fonzie was featured in the lead image? Believe it or not, Happy Days also had trouble with the censors about one issue- Fonzie's leather jacket.
The Fonz looked like a total Potsie without his leather jacket, but censors claimed only criminals wear a leather jacket when they're not riding their bike, so show creator Garry Marshall started working a motorcycle into every scene.
