"Yet, it feels unfinished, wanting." --Edd This list is incomplete. Please help the Ed, Edd n Eddy Wiki by expanding it.
In fiction, the fourth wall refers to the imaginary barrier between the characters and the viewers. The term derives from theater and would describe the set having three walls. With the fourth wall being the camera.
Whenever the characters acknowledge they're in a work of fiction, they're breaking the fourth wall. Usually by looking or directly talking to the audience, or making outside references to whatever medium they're in.
Ed, Edd n Eddy is particularly notable for breaking the fourth wall. Very often they will do it by talking about the technical aspects of the show and animation in general.
List of fourth wall breaks
In the intro of each episode, the Eds move the camera and then crash into it, after which static appears.
After Rolf washes dishes, Eddy considers this a crime and says "25 cents, or 25 days in the pokey!" Edd interrupts and tells him "Wrong cartoon, Eddy." This is a reference to The Quick Draw McGraw Show by Hanna-Barbera.
Ed says "I should have all the feeling back in my feet after this word from our sponsors!" Edd, now forced to carry the heavy slab of the sidewalk that originally injured Ed, then groans "Curse broadcast commercialism!" The half-hour episode's first part then immediately breaks for commercials.
Towards the beginning of the episode, Wilfred bites the edge of the next scene and drags it into place.
At the end of the episode, Edd says "An iris-in would be appropriate now, don't you think?" The screen then goes black and shrinks onto a circle of Eddy. This is how many cartoons end. In addition, after Eddy is consumed by the black screen, Edd adds "Thank you."
Eddy breaks the fourth wall (and refers to "Ed in a Halfshell") by saying: "Oh yeah! Didn't we win an Emmy for that episode?" Edd then says "Hardly," referring to the fact that they did not win an Emmy Award but were nominated for a Leo Award in 2001 for that episode. This is also the first time an episode is referred to as an "episode" rather than as a "show."
Near the end, after Sarah and Jimmy take a picture of the Eds in fairy tale costumes, Edd says "Well, best prepare our fairy tale for school tomorrow. It's gonna take a lot of explaining to get out of this plothole."
During the bus ride, Edd and Eddy enter into an argument. At the end of it, Ed says, "Don't touch that dial, kids," imploring the audience not to change the channel out of boredom after hearing Edd's long winded complaint.
At the end of the episode, Rolf says "Yes, Rolf finally feels safe enough to appear in this episode." This is the second time a character refers to an episode as an episode instead of a "show" to break the fourth wall.
The Eds escape by finding a car key inside a peanut in an "In Case Of Movie Break Glass" container (a reference to many cases of the sort, usually saying "emergency", not "movie"). After they open it, the find the peanut, to which Ed replies "Cheap movie."
After Eddy gets out from under the billboard that recently crushed him he states "I'm starting to hate slapstick", referring to a comedic style the show frequently employs.
At the end of the movie, as all the kids finally accept the Eds, Edd states that it only took 130 episodes, 4 specials, and a movie for them to become popular.
During the bonus sequence during the credits, Plank throws a wrench into Jonny's scheme for Cul-de-Sac domination by "stating" that the movie is over to which a confused Jonny replies "What movie?"
