The original pilot for The Simpsons was Some Enchanted Evening, which featured Penny Marshall as the diabolical Ms. Botz, who turns out to be The Babysitter Bandit.
When the finished episode was submitted from Korea, the animation looked terrible and Fox was reluctant to air it. Instead, Simpsons Roasting on an Open Fire became the first episode that would air. Some Enchanted Evening would be reshot and become the first season’s season finale.
