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."
