I absolutely love fairy odd parents. From experience kids do sit through it, and as a matter of fact, you can make a grown up like me sit on it as well since it is VERY funny.
There's this anime thing called "Digi Charat Nyo" if you actually have a station with it, it is also another fun one.
Grim adventures of Billy and Many / Kids next door are nice imho.
If you are a parent, do yourself (and your kids) a favor, and get DVDs of all shows, your kid should really get to see the old stuff, just to avoid him/her to become too focused on novelty, I think no kid should be neglected the right to enjoy the pink panther, pinky and the brain, garfield, animaniacs, and some other great shows that don't show anymore (unlike bugs bunny stuff / Scooby doo which is still aired)
I watched Square pants bob the other day and it was ok, Dora the explorer is quite terrible imho.
And btw I really hated Scobby Doo, really. I just don't get it why they keep airing it and making new versions.

On action stuff: Ben 10, whoever invented that should be... reallly, I hate that one. But there are some nice ones around there like Justice League, just need to dig more...
