A very weird movie that i watched 10-15 years ago on TV. Actually I can’t fully remember the whole movie plot but the movie seem like not a main stream movie.

Something like the main protagonist get himself into a simulated world with a lot of weird things and he try to get out. There is a scene where he inside a house of simulated sitcom. Inside the house, he need to keep making jokes to keep the simulated audiences laugh to survive. The audiences are living bodiless heads who keep watching the protagonist via a TV .
