Creator's Favorite: Rolf is Danny Antonucci's favorite character. Also an Author Avatar, since Rolf's backstory and different traditions are loosely based on Antonucci himself and his relatives (Antonucci is part of an Italian immigrant family).
Cross Dressing Voice: Kevin, who happens to be the most masculine, toughest male character on the show to boot, is voiced by a woman (the same one who voices Marie Kanker).
Keep Circulating the Tapes: "May I Have This Ed?" and "Look Before You Ed", the only episodes made for the show's sixth season before Danny Antonucci decided to scrap the remainder of it for the movie, aren't available on iTunes or any other digital service.
Missing Episode: Three. "Special Ed", which was finished but never aired due to (depending on who you ask) being either too surreal or "too real" for television. Not much else is known about it other than the fact that it might of been A Day in the Limelight for Ed. The other two, "Luck Be an Ed Tonight" and "A Room and an Ed" may have never even left the planning stages.
An episode called "Special Ed" was slated to air, but was scrapped for being "too real." No one knows what Antonucci means by that, but that won't stop fans from guessing. Rumors state it was going to be A Day in the Limelight for Ed. note Although "special ed" is short for "special education" which is, not exclusive to, but most commonly associated with kids who suffer mental retardation. For those curious, those with with focus or emotional issues — such as attention deficit disorder or Aspergers' syndrome — can also end up in special education.
It's hard to believe, but this show was originally pitched to Nickelodeon as a Nicktoon. While Nickelodeon has a lot of radar-dodging shows, they don't go as far with it as Cartoon Network does (possibly because they don't want another Ren and Stimpy on their hands), and Antonucci knew that if Nickelodeon accepted the show, a lot would have to be changed for content/demographic appeal/general Executive Meddling reasons.
Write Who You Know: All the characters are based on either facets of creator Danny Antonucci's personality, family members, or people he knew growing up. Yes, even those based on the Kanker Sisters, Kevin, and Eddy's older brother.
