In "A Streetcar named Marge" Llewellyn Sinclair sometimes wears clothes that resemble a Scientology uniform. The interesting point about that is that "The Joy of Sect" was made later, so why is he wearing that ? Did they just reuse an old sprite, or is there a deeper meaning ? I read, they planned to mock Scientology earlier, but delayed "The Joy of Sect" to avoid trouble beacause of the Heaven's Gate mass suicide, but was it delayed so long ? It appears, like Llewellyn Sinclair resebles a real life Scientologist. Note, before I found this wiki, I assumed Llewellyn Sinclair and The Leader are the same person.
