Check out the Lost Media Wiki’s article on "Luck Be an Ed Tonight"/"A Room with an Ed"!!!!!!!!!
Ed, Edd n Eddy.
"Luck Be an Ed Tonight" and "A Room and an Ed" are two half-episodes of the fifth season of Ed, Edd and Eddy that were never released to the public and possibly never even made. The episodes were both announced through a Season 5 "sneak peek" list posted on the Edtropolis news page in 2005.
"Luck Be an Ed Tonight" was about Ed discovering that it was his lucky day according to his horoscope, which resulted in Eddy trying to milk it for all it was worth, and the episode that it was going to air with, "A Room and an Ed", was about Sarah and Jimmy kicking Ed out of his room so that they could turn it into a personal playroom of theirs, and Eddy training Ed to be more assertive. Not too much else is known about these episodes, including why they were scrapped and if they were finished or not.
