This is completely a Star Trek episode when Kirk & Spock beamed down to a planet insane asylum, the prisoners had taken over I think the main character wished to be called lord Garth, lmao. "You wrote that!" Anyone who is familiar with that episode will know that quote.
shareThis movie was based on a short story by Edgar Alan Poe called "The System of Doctor Tarr and Professor Fether" so it's possible that the Star Trek episode you're talking was inspired by the same story

In an episode of the Scottish sitcom 'Still Game' the two protagonists visit a mental hospital in an attempt to have their friend released and get a short tour by a man in an orderly uniform. At the conclusion of the tour the man pulls a shoe from inside his jacket and begins to daub face paint on himself with what looks like excrement before running off down a hall laughing, leaving the two of them in the middle of a hospital as it finally dons on them that all the doors have been wide open.
