Another victim of the “Saturday Morning Post 11 AM Curse”.

Most TV networks then started college football programming at noon. Then the local stations would dump the 11:00 and 11:30 cartoons for their pre-game show. I remember Big Guy and Rusty, Gargoyles:the Goliath Chronicles, and Santo Bugito all being victims of this.
Sometimes, the bumped shows would be shown the following Sunday or Saturday morning at like 6 am. Usually though, they just weren’t shown.
