"Special Ed" was an episode of Ed, Edd n Eddy that was put into production, but never completed, and thus never saw the light of day.

Very little is known about this episode and the only evidence we have of it even existing is an interview, in which Danny Antonucci reminisces after talking about the show capturing childhood spontaneity; he says the episode didn't go through because "It was just too real".[1] It is possible that it would have been an episode that focused directly on Ed, and most likely would have revolved around the reason why Ed is a Simpleton.
