Original Air Date: February 10, 2003
Picking up where we left off, Abe asks Cleo to the prom, to which she obviously says yes. Scudworth regains consciousness after fainting at the news that the the Secret Board of Shadowy Figures is coming to collect the clones and terminate him on prom night, and has amnesia. Mr. Butlertron is able to restore his memory all the way up to that last essential detail, unable to find a way to tell him. Gandhi assembles a troop of dateless nerds to go to prom as a posse in hopes of scoring ten women each. Joan flaunts her new makeover around school, but when Abe still fails to get in touch with his feelings for her, she agrees to go to prom with JFK to make Abe jealous. Somewhere else, the Secret Board of Shadowy Figures takes off to collect the clones
The principle cast makes it to prom, which is being held in the school meat locker. Scudworth rigs the prom king election so that he'll win it, but before his win is announced, John Stamos arrives to check up in his "old friend", and inadvertently steals the attention away from Scudworth. Abe walks over to Joan and tells her that her date JFK is a lucky guy to be at prom with her, only for Cleo to interrupt them to drag Abe to bed to have sex. When they get in bed together, however, Abe can only see Joan's head on Cleo's naughty bits, and discovers that he's in love with Joan. Joan goes outside to get rid of her makeover stuff, and JFK joins her, telling her that she's beautiful when she's not trying to be a giggly slut. Stamos is crowned prom king, but gives the crown up to Scudworth when he gets upset. Scudworth, however, uses the pointy crown to stab Stamos in the eye and still claim it.
Abe runs to Gandhi and tells him he's in love with Joan. Gandhi and Marie Curie eventually end up together, but decide to remain abstinent. It is then that the Secret Board of Shadowy Figures arrives, but John Stamos tells them that they can't take the clones or terminate Scudworth before the prom king starts a conga line, to stall them. Scudworth realizes that Stamos is just a genuinely nice guy, and decides to lead the Secret Board of Shadowy Fidures into the quick freezer to trap them. Abe eventually finds Joan in the quick freezer bed with JFK, having just had sex. The two exchange a heartbroken glare as Scudworth leads the conga line containing the Secret Board of Shadowy Figures into the quick freezer. Scudworth then runs out and Stamos makes a Heroic Sacrifice to stay in the freezer and turn it on, trapping everyone inside. Abe tries to tell Joan that he loves her, but is frozen in mid-sentence, along with basically all the other main characters.
- All Love Is Unrequited: A theme throughout the series, but comes to a head at the end of this episode: Joan still doesn't get Abe, and Abe is frozen before he can tell Joan that he loves her.
- Beautiful All Along: Subverted. Joan was never unattractive, but only got attention when she started dressing like a tramp. When her plan to get Abe's attention with it fails, JFK takes her aside and tells her that he likes her as she is. Similarly, Marie Curie is grotesquely deformed, but it doesn't stand in the way of Gandhi's interest in her.
- Be a Whore to Get Your Man: Sincerely mocked.
- Bittersweet Ending: Just barely. Scudworth and John Stamos stop The Board of Shadowy Figures from repossessing the clones and Scudworth gets away, but everyone is left in suspended animation forever, just as Abe and Joan were about to confess their feelings for one another.
- The Bus Came Back: Everyone who had previously appeared on the show (with the exception of the clones parents), reappears either as part of the crowd or the Shadowy Figures group, including the celebrities, Skunky Poo and even Geshi. Which means they're trapped with everybody else in the freezer at the end.
- Colon Cancer: While regular episode titles have one colon in them, they made it prominent that this was the season finale by adding two more.
- Creator Cameo: Abandoned Pools, who wrote and performed the theme song, cameo as the prom band.
- Cue O'Clock: "Sex O'Clock."Cleo: It may have sounded like I said the number six, but instead I substituted the more suggestive word... sex.
- Cut Short
- Digital Bikini: A plot-relevant example with the floating Joan heads in front of Cleo's junk.
- Dope Slap: Gandhi gives one to Abe when he asks him if he thinks Joan returns his affections.
- Everyone Can See It: After finally, finally, finally realizing that Joan might possibly have feelings for him, Abe shares his amazing revelation with Gandhi, who just gives him a knowing look in response.
- Eye Scream: A furious Scudworth stabs the prom king crown in John Stamos eye, completely destroying it, much to the audiences horror. He then wears the blood-splattered crown and laughs like a lunatic.
- Grand Finale: Zig-zagged. The creators weren't sure whether or not there was going to be a second season, but considering all that happened during the first one knew there probably wouldn't and felt that the only funny way to end the show is to leave everyone literally frozen in place.
- Heroic Sacrifice: John Stamos flash-freezes himself in the meat locker with the other character to Scudworth can get away.
- I Like My Humping Like I Like My Martinis: Dry.
- Karma Houdini: Invoked with Scudworth, who planned to steal the clones from the Board of Shadowy Figures and use them as amusement park attractions, but is able to get away by leaving both parties in suspended animation.
- Locked in a Freezer: And left there forever.
- Nipple and Dimed: Parodied. When Abe walks in on Joan naked in bed with JFK, the first thing we see is a close up of her breasts, with the words "Nice try" in place of her nipples.
- Nice Guy: John Stamos turns out to be one of these, despite Scudworth's hatred of him. He genuinely didn't realize that him calling Scudworth every year to reminisce about the time he won prom king was setting him off so badly (not helped by Scudworths politeness during the actual phonecalls), and when he drops by to visit Scudworth at prom, the audience loves him and elect him prom king again. When Scudworth calls him out, Stamos even offers him the spot. Scudworth responds by trying to murder him with the crown.
- No-Sell: After Abe ditches her, Gandhi tries to get with Cleo by putting on a fake beard and top hat and walking in on stilts. She isn't fooled for a second and tells him to get lost.
- Say My Name: Stamos!
- In-Universe. Cleo demands that Abe say her name when they're about to have sex and he can't stop saying Joan's name. This is how he figures out that he's in love with Joan.
- Screw This, I'm Out of Here!: Mr. Butlertron once the Secret Board of Shadowy Figures arrives.Secret Board of Shadowy Figures: Assembled students of Clone High, your collective asses now belong to us.Mr. Butlertron: Oh about that. Uh... I'm gonna take my vacation time now. [leaves]
- Sitcom Arch-Nemesis: Stamos!
- Unknown Rival: Stamos!
- Special Guest: STAMOS!
- Stealth Pun: This animated show ends with all of its main characters frozen where they stand. They're in suspended animation.
- Toplessness from the Back: Cleo is shown this way just as she and Abe are about to consummate. Subverted in that she does eventually get completely naked, but when shown from the front, her naughty parts are covered by floating Joan heads.
- Wham Episode: A mostly unintentional example. The season ends on a massive cliffhanger which was never resolved due to the show's cancellation.
