From the TV Tropes page (see Urban Legends section):

"In 2001, a rumor about an Missing Episode known only as 'The Scarecrow Boy Episode' surfaced. The story is that Sarah puts on a play - her own version of The Wizard of Oz - casting herself as Dorothy, Jimmy as the Tin Man, Eddy as the Cowardly Lion (apparently he was also tied to a chair the whole time because he kept trying to walk out on Sarah), Ed as the Scarecrow, and Double D as the director. Sarah became outraged with Ed continuously blowing his lines, and ended up kicking and locking him out of the house (while still in costume); when Kevin and other kids in the cul-de-sac see Ed roaming around, they keep calling him 'Scarecrow Boy', which somehow causes Ed to grow stiffer and stiffer each time he heard the name. Eventually, the episode ends with Plank nestled into the ground, and Ed standing on top with his arms straight out, as if he has become a real scarecrow. There is absolutely no evidence whatsoever that remotely proves such an episode exists, though many fans swear to have seen it, and that it only aired once."

Pretty much this would be considered creepy because at the end Ed presumably has turned into a real scarecrow, and therefore is dead. Plus it has the only-aired-once theme found in most Lost Episode pastas.
