Legendary nice guy Mister Rogers goes to the TV studio where he meets The Incredible Hulk himself: Bill Bixby. Bixby shows him the set and explains that what takes place is just pretend – make-believe.
He goes on to show a few clips from the show and talk about how he liked to pretend when he was a child. He also mentions that he would get angry from time to time when he was younger:
