The Wishing Well is a scheme that Edd came up with in "One Size Fits Ed." The crux of the scheme was a meticulously made forgery of a well that, although only a few feet deep, looked to descend deep into the earth. Sarah and Jimmy both fell for it, and each dropped a quarter into the well to make a wish. Although the scam was successful, Edd's point wasn't to make money, but rather to teach Eddy about the possible usage of and science behind optical illusions. Before he could go too far into detail, though, Ed interrupted, telling them that he was a sumo wrestler. This, combined with Eddy remembering Jimmy's wish that he was a star, spurred Eddy to try and find Jimmy so that he could make him into a sumo wrestler, and the scam was abandoned.
