Hanna-Barbera sponsored an Ed Grimley look-alike contest midway through the first season, which was won by 10-year-old Matt Mitchell from Des Moines, Iowa.
Episodes of the show often featured Ed Grimley in several adventures, which start out as mundane, but turn very surreal and cartoonish, interspersed with science lessons from The Amazing Gustav Brothers, Roger and Emil, and a live-action segment with a "scary story" titled The Count Floyd Show presented as a show-within-a-show by Grimley's favorite television host, SCTV's Count Floyd (played by SCTV cast member Joe Flaherty).
The Amazing Gustav Brothers: Roger and Emil talk about centrifugal force by visiting the amusement park by going on the Screaming Banshee of Hades.
Ed and Wendall, the annoying brother of his crush—a ditzy amateur actress named Miss Malone—go on an amusement park rocket ride, taking them to another planet which is ruled by an alien queen who sounds like Bette Davis.
