The Dodgeball Incident was an event that happened to Edd in the past. This event was first referenced in the episode "Ed in a Halfshell." The incident is not seen in the series, but according to Edd he seemed to have been injured and/or humiliated during a game of dodgeball, and he has since feared going to gym class. In fact, the threat of playing dodgeball frightened Edd immensely, and when Eddy was ready to throw the ball at him, he collapsed to the ground, catatonic. Although he is seen in gym class in Ed, Edd n Eddy's Hanky Panky Hullabaloo and in the episode "Cool Hand Ed," he often seems nervous. The Dodgeball Incident is probably the reason why Edd hates most sports, if not just one of many reasons.
- Edd: "Eddy, wait! I-I have a history with this game. I-what's that? Deep flashes, Eddy, like tentacles! Strangulating every rational nerve! Oh, I'm reliving it, Eddy!"
Eddy: [shows ball with bucktooth Edd drawing on it] "But's it's got your face on it, Double D."
Edd: "Listen to me, Eddy!" [Eddy prepares to throw the ball] "Eddy?! It's gym class all over again!" [wails]
