There's that kid from the cancelled cartoon the Oblongs. Had one twitchy eye and a blown retina if I recall. Would run crazy all through the show. Stereotype but funny anyway. I guess Homer and Bart Simpson too - unless it's all about them and totally fascinating they couldn't care less.
Careful folks not to overdiagnose cartoons! That's - well it's creepy. I hate those articles in magazines trying to analyze cartoon characters and other fictional characters. Takes all the fun out. Face it - unless the character was designed to have certain traits we just project what we wish or dislike onto them.
My kids watch Ed, Edd & Eddy I certainly believe they have ADD/ADHDOh Adult Characters! OOPS!
