Superman has been referenced many times throughout pop culture, including song lyrics, mentioned in other movies, and various TV shows over the years. In 1970, the “Bewitched” TV series aired an episode titled “Super Arthur” (Season 6, Episode 20) in which, to help with Uncle Arthur’s ailing magic, Doctor Bombay gives him a pill that makes Arthur turn into anything he thinks of including the character Superman.
The official “Bewitched” YouTube channel posted the following clip from the episode, which first aired on February 5, 1970.
