You've never seen the Room?
Quick. Drop what you're doing. Get your best, raunchiest, most hilarious friends together, and get them as drunk as humanly possible. Then watch the Room together.
After that, read the book The Disaster Artist. It's an intense and bizarre and utterly hilarious book about the making of that movie, telling the story of the guy who played Mark in the movie. They made The Disaster Artist into a film and it's alright, but it leaves out tons of hilarious details that were in the book.
