Ah! Ed, Edd, and Eddy, one of Cartoon Network's most popular shows. I watched this show growing up, and played the flash games online. Hell I even played Fusionfall! My favorite character is Ed (I used to have a massive crush on him when I was like 5-7 years old lmfao) and he still remains my favorite, though I've grown on Edd and Nazz as well. I don't like Sarah though, she's kind of a huge bitch for like no reason to everyone except Jimmy.
The show started declining in Season 5 though. All the characters were flanderized to hell and back. So it's no surprised that's where it ended.
