Elroy's Mob

In the morning, Jane sends Elroy to Little Dipper Elementary school, Judy Jetson goes on a date with Ricky Rocket on a hoverboard sky skiing, and George takes Astro to play with the dogs.

At school, Elroy solves a complex math problem in his classroom. School bully Kenny Countdown watches the billionth rerun of The Flintstones on his TV watch during class. The teacher confiscates his watch and is mocked by Kenny, due to a short in the teacher's transistor. The teacher says Kenny won't be laughing in a minute, as she passes out the weekly report tapes. The teacher gives Elroy his tape, with straight As. As Elroy is flying around the classroom happily, he is instructed to sit back at his desk. Kenny pushes him out of the way, and Elroy lands on the floor. The teacher assures Elroy that Kenny will be punished when his parents hear his grades: four Ds, an F, and an H. Not only can't Kenny erase the tape because it's strong against magnets, but he knows what will happen the minute his father hears the tape. Kenny pulls a prank on Elroy and switches the grade tape reports to avoid punishment.

Elroy is excited to show the grade report, but when he gets home, his parents and sister are disappointed with Elroy. Elroy tells the truth, but nobody believes him except Astro. George sends him and Astro to timeout in his room with no supper pills.

Kenny Countdown's dad calls; he is angry with Kenny's lie and tells him to confess the truth to George and Jane before he punishes him. Kenny tells the truth about the tape report; now realizing Elroy was telling the truth, George and Jane feel guilty over not believing him. They go to make things right, but find a note saying that both Elroy and Astro had run away from home, and they drive to the police station.

Meanwhile, the Sky police told Elroy and Astro to fly home because of a robber named Mugsy Megaton and his gang. Mugsy and his gang are trying to rob a jewelry store, but they tricked Elroy and Astro into joining their club and had Elroy open the door for Mugsy to steal the jewels. Later, Mugsy and his gang kidnap Elroy and hide in the Skypad apartment. George and Jane both fall into Mugsy's trap, and he ties them up. Astro unties himself and goes to the police for help. They arrive and arrest Mugsy, and Astro saves the day.

Trivia[]

This is the last episode of the 1960s incarnation and uses the original version of the show's theme song. When the show was revived in 1985, a re-recorded version of the theme song was used.
- It is also the last episode with classic animation. Despite this, the theme song continues to have this kind of animation when the show was revived in 1985.
This episode was adapted into the book Elroy and the Space Bandits.
The plot is similar to that of the Scrappy and Yabba Doo episode "Runaway Scrappy" two decades later; both Elroy and Scrappy run away after feeling unwanted and unknowingly help bank robbers when the robbers trick them into thinking that they're someone else.
The Flintstones episode that Kenny watched on his watch was "The Swimming Pool".
On MeTV and MeTV Toons, near the beginning of the episode, the whole sequence of George getting ready for work and taking Astro to dog school was removed. Also, when George says he feels "lower than a Martian midget", the word "midget" is muted.
