The interviewer

This is about a talk show host. He does nothing but interview people but everyone who comes on is written a script. Most of them made fun of the host, some just consistently got his name wrong, some thought he was a woman, some sat in his chair and interviewed him. He had an assistant that sometimes would sit in the chair and due interviews, and many times he would ask the guests a question and they would ignore him and talk to his guest host. The guests would preview movies they weren't in, movies that came out 20 years ago and fake movies. But it was all done completely seriously and there was never a nod to the audience.
