"Ed Overboard" is the 7th episode of Season 4 and the 84th episode of Ed, Edd n Eddy. In this episode, Lee and Marie kidnap Ed as a gift for a highly upset May after they ruin her appearance in a prank. The two remaining Eds must utilize all available resources to get their friend back.
In the Kankers' trailer, May is ready to receive a makeover from her sisters. When it's over and she looks in the mirror, however, she finds that instead of making her beautiful, her sisters have instead pranked her and wrecked her looks. May flies into a terrible tantrum and starts throwing things at her sisters, who hide behind the sofa. This doesn't deter May, who continues to throw things until she finds herself holding her Ed doll. Seeing this, she breaks into tears, afraid that Ed will never love her. Marie and Lee, feeling slightly remorseful, try to comfort her.
Meanwhile, the Eds have set up a scam based on selling arts-and-crafts outside Edd's House. Ed is perfectly happy to make macaroni art, but Eddy is irritated, as the scam hasn't yet brought in any paying customers. He and Edd get into an argument over the profitability of such a venture and its' chances at success when they're distracted by Ed having glued his head to the table. At that moment, things get disturbing when Lee and Marie appear and, without much ado, carry off the table. Edd is freaked out by this, as is Eddy. Their reactions are polar opposites, however; while Edd wants to help out his kidnapped friend, Eddy thinks that it would be better to just pretend they haven't seen anything. An offhand comment to this end gives Edd an idea, however, and he drags Eddy away from the arts-and-crafts table.
At Rolf's place, Rolf is collecting tree sap. Edd and Eddy run up, Edd out of breath and trying to explain what's going on. Rolf takes this in stride and then jumps into his barrel of sap. Edd is perturbed by this, only to be caught by surprise when Rolf leaps out of an oil barrel behind them, clothed in his Urban Rangers uniform. He then declares that the Urban Rangers will rescue the missing Ed-boy and proceeds to call them. Eddy, upset, is about to deliver an ultimatum to Edd about the Urban Rangers when Jonny, Jimmy, and Plank rush in, trampling Eddy along the way. Rolf then outlines the situation to them, but tells them there is no badge, much to their surprise. Jimmy and Jonny are taken back until Rolf shows them their reward: the Freeing of the Fool Pewter Medallion! Jimmy and Jonny ooh and ahh over this, but Eddy is disgusted that they'd only work for badges. Rolf is irked by this, and when the time comes to go out on their mission he holds Eddy and Edd back, declaring it official Urban Ranger business. Edd makes a case for allowing them to help, as Ed is their friend, and Rolf relents, deputizing them into Rangerhood.
At the Park n' Flush, Ed has been tied to a tree, and May is torturing him. When the six rescuers come in, Eddy sniggers at his friend's predicament. Rolf then sets out to execute the plan. He starts by going over and calling attention to the wreck that the Kankers' grill has become. He then proceeds to start polishing it. Lee and Marie naturally start to swoon over a man in uniform polishing their grill, and Lee grabs May so she can enjoy the show. While the Kankers observe Rolf's work, the other three Rangers go over to Ed and start to untie him. Ed is naturally happy about this, but doesn't get the point, suggesting that they go for help. Jonny tries to tell him that they are the help, but Ed ignores him, instead saying that he'll distract the Kankers so they can go for help. Ed begins loudly singing, and naturally enough, the Kankers are distracted. Unfortunately, they're distracted by Ed, and they catch the rescuers in the act, causing Ed to point out that they weren't supposed to get caught. Lee notices that the Rangers are wearing the same uniform as Rolf, and after a few shoddy excuses they implement "code yellow evasive maneuvers", which consist of catching a quick sickness and falling down dead.
Eddy laughs at this pitiful display and then tells Edd that they're going. Edd refuses, and when pressured, stands strong, saying that they won't leave without Ed. Eddy then gives in, although he threatens to beat up Edd if they get caught, and while the Kankers are distracted by the Urban Rangers, the Eds go out and stealthily uproot the tree Ed is tied to.
Later that day, the Eds are in the Playground, and Edd is cleaning the crayon stains and kiss marks off of Ed. While cleaning Ed, he finds a bandage on his back. At first he is worried that the Kankers harmed his friend, but upon hearing it was Ed's doing, decides to peel it off. Underneath is a cookie, which Ed eats, claiming he saved it. Edd is initially disgusted by this, but soon, remembering who Ed is at heart, claims it's good to have Ed back. He is then distracted by Eddy guffawing at the fate of the Urban Rangers, and they get into an argument. Meanwhile, the Urban Rangers capture Ed and leave, seeking vengeance for the humiliation that was visited upon their bodies. Good and fed up, Eddy declares that he's leaving, and goes in the opposite direction while Edd tries to convince the Rangers not to do whatever they're about to do to Ed, instead preferring Eddy as a target.
In a fit of rage, May throws a Vancouver snow globe at her sisters. This references the location of the show's production company, A.K.A. Cartoon.
The Kankers use a "Toomey" brand cigar box to hold their lipsticks. The brand name is a reference to Cory Toomey, one of the series' prop designers.
Also inside the box is a hand drawn picture of one of their dads.
Eddy breaks the fourth wall when he says, "I'd swear, but standards won't let me."
Eddy references Harry Houdini after Rolf rapidly changes into his Urban Ranger uniform.
When Jimmy learns that there will be no badge for freeing Ed, he states "Something smells rotten in Denmark." This is a reference to the Shakespeare play Hamlet, in which the character Marcellus states, "Something is rotten in the state of Denmark."
