Oh yeah, I just remembered that I liked not one but two of Cartoon Network's kids shows, Dexters Labatory and (unfortunatly) Power Puff Girls, I know that is so not Sheldon J. Plankton, but that show was just show f***in' funny. Also, CN has Star Wars Clone Wars, which is an awesome show when you watch all the episodes together and not in the 5 minute blocks (my friend has the DVD, the DVD is the way to go). However, when you count old school Nick like Rocko and Angry Beavers and Action League Now and Zim, combine that with Spongebob, and Nick is probably just a little tiny bit better.
Also, I almost forgot, CN now has Camp Lazlo, which I have not yet seen but have high expectations for because it was created by Rocko's Joe Murray. I want to see this show. If that is good than Cartoon Network is full-fledged better.
