Elroy looks forward to the evening when his parents hear the good grades Ms. Brainmocker gave him. When he accidentally gets a report tape mix-up all thanks to his sneaky, underachieving classmate, Kenny Countdown, and gets 4 D’s, an F, and an “H”, his family doesn’t believe him, so when he gets punished, he and Astro run away and join a mob run by Muggsy Megaton and the Jetsons set out to find him when the mistake is cleared up. Note: A clip from The Flintstones is shown in the beginning of the episode.
