The Grim Adventures of the Kids Next Door

The Grim Adventures of the Kids Next Door is a special crossover episode between The Grim Adventures of Billy & Mandy and Codename: Kids Next Door that aired on November 11, 2007. In addition to the two titular shows, several characters from other shows cameoed, including the Eds, who had the most screentime of any non-Billy & Mandy or KND character. The show is the last episode of The Grim Adventures of Billy & Mandy to air before the Halloween special "Underfist" and aired between the Kids Next Door episodes "Operation: G.I.R.L.F.R.I.E.N.D." and "Operation: C.A.R.A.M.E.L."

Plot
Billy rips his father's lucky pants, so he calls Ed, Edd n Eddy's Pesky Problem Fixers to help him out. When he reveals he's broke, however, Eddy angrily tells him to call the Kids Next Door, as they work cheaply. Billy takes Eddy's advice, but this leads to a series of mishaps for Numbuh 1 that culminate in Mandy taking over the Kids Next Door and him being forced to work with "some freak in a Halloween costume."

Quotes
Billy: [horrified] "Dad's pants! What do I do? Dad's gonna sell my organs if he finds out I ripped his lucky pants!" [determined] "There's only one group of kids who can help me now." [At Ed, Edd n Eddy's Pesky Problem Fixers, the phone rings.] Ed: "Hello!" [Eddy picks up the phone.] Eddy: "Ed, Edd n Eddy's Pesky Problem Fixers! Got a problem that's pesky? We'll fix 'er, for just one lousy quarter!" ''[Muffled gobbling comes from the telephone. Eddy gives it a look.]'' Eddy: [angry] "WHADDYA MEAN YOU'RE BROKE? Hey! If you're looking for charity, call Kids Next Door. They're cheap." [Eddy angrily hangs up the phone.]
 * [Billy has just accidentally torn a hole in his father's pants with Grim's scythe.]

 * Ed, Edd n Mandy (crossover between Ed, Edd n Eddy and The Grim Adventures of Billy & Mandy): In this poster, Ed and Edd are running in fear as Mandy waves around Plank, who has a nail driven through his forehead. This poster suggests that in the show, Mandy will have taken over as the resident megalomaniac and acts far more violent than Eddy.

He is dressed as Numbuh 3. This poster suggests that in the show, Sunny Bridges will join the Kids Next Door in order to help fight adult tyranny.
 * My Gym Partner's A Mandark (crossover between My Gym Partner's a Monkey and Dexter's Laboratory): In this poster, Jake Spidermonkey and Mandark Astronomonov are seen swinging on a vine, presumably headed to class. The poster implies that Mandark will have taken Adam Lyon's place in the show.
