Good question... I am not sure. Ed Edd n Eddy had six seasons while Samurai Jack had five.

Is "longest running" show based on the year it started to the year it ended not taking into account the amount of seasons? Even if that may be so... Samurai Jack's last season aired on Adult Swim like you said, so it may not count for Cartoon Network's longest running show anyway. :P
