Comedian Rich Little comes in and demands to take over ALF's job of hosting because he's botched it up so badly. ALF refuses and instead shows more flashback segments of his daily life with the Tanners. Ed and Rich are steamed, especially since the Pope is still waiting backstage to be introduced.
Finally, after waiting the duration of the show, ALF introduces the Pope. Just as the spiritual leader sits down, ALF wishes everyone "goodnight." While the credits roll, the red telephone on Johnny's desk rings and one can assume that it's Johnny calling, wanting to fire ALF and everyone else involved with his show's mishandling.
