The Super Mario Bros. Super Show! episode E.C. The Extra Creepy
September 25, 1989
The sixteenth live-action segment of the Mario TV show, broadcasted along with the cartoon episode "Toad Warriors", is about Mario dating a girl named E.C. assigned to high trough a dating computer program. After Mario and Luigi notice her strange behaviour, they finally find out that she's actually an extra-terrestrial robot, something that still doesn't prevents Mario from loving her. In the end she's called back to her space ship, but before leaving she gives Mario her heart as a gift.
The episode's title, as well as the character's name, are obviously based on the movie E.T. the Extra-Terrestrial. Despite this, however, the episode's plot has nothing to do with the movie, apart from being about an extra-terrestrial being befriending a human.
DiC, that created the Mario TV show, holds no right over Universal Pictures' E.T., in fact they only featured a minor reference to the movie.
