Finding dark secrets on certain shows is nearly impossible—in some cases, it is impossible because there are none. It is possible to believe in some very nasty notions regarding Ed, Edd, and Eddy. Even if the hypotheses put up by certain enthusiasts are not supported by evidence, they are worth considering nonetheless.
As a way of explaining why they never go to school, fans of Ed, Edd, and Eddy have hypothesized that the three main characters, Ed, Edd, and Eddy, may be trapped in purgatory. This is a gloomy theory that has survived throughout the years.
