Spaceballs The Animated Series
The Skroobinator
S1 E3:
President Skroob is up for re-election and he's way behind in the polls so he and Dark Helmet concoct a ludicrous plan to travel back to Earth 1984 to kill his opponent's great great great great... grandmother. Yogurt senses a disturbance in the Schwartz and alerts Lone Starr and Barf who journey back in time to save the day but in the end Skroob has the last laugh.
