Adults

Adults are never seen in the series, though they have been to the Cul-de-Sac. However, adults seem to have an off screen presence that seems to affect the main characters whenever they are near. Kevin's dad appears to work at a nearby jawbreaker factory, it is possible that an adult runs the Candy Store and Ed's mother seems to have blond hair. In one episode, Edd calls the parents back to the cul-de-sac, showing that the parents are all away. However, Sarah constantly threatens to tell her mom on Ed and the characters sometimes get grounded, proving that the parents can come and go when they need to. In one episode Eddy Is thrown out a shop by an adult after he has the wrong currency. Rolf has been heard talking about his Nana numerous times.

Trivia

 * Plank's Parents are technically the only parents to appear in the show.
 * Eddy's dad and Ed's mom seen in "Mission Ed-Possible" but only their arms were showing.
 * Rolf's relatives were shown during "The Eds are Coming" but only as silhouettes.
 * In the episode "Smile for the Ed" the school photographer's arm and Eddy's mom's arm were shown.
 * It is also shown that their mother is in some aspects like May (shown in Hanky Panky Hullaballo when May tromped on Marie and she responds "Now I know who got Mom's genes").
 * The Kanker Sisters mother seems to have a low opinion on men. Judging by the various insults she has directed towards men.  This may be a direct hint that she divorced three of her husbands (i.e. Butch, Bubba, and Rod)
 * The Kanker Sister's Mother seems either hypersensitive or bad-tempered, maybe even both.
 * Double-D's parents communicate to him by using sticky notes.
 * The Adults (mostly Eddy's and Ed's parents) seem to be huge, and tall (even taller then Ed) and get angered quickly.
 * Santa Claus briefly appears in "Ed, Edd n Eddy's Jingle Jingle Jangle." He is apparently the only adult who's voice is heard.
