I love FOP too. My daughter watches it, and I sat down and watched it with her, and I was excited because it wasn't annoying. Now I'll even watch it on my own.
Oh I love this cartoon. I watch it with my son everyday on Nickelodeon. It's one of our favorites. We actually just finished watching it about 10 minutes ago. It was the one where Timmy wishes that his parents had friends. So Cosmo and Wanda make themselves into adults. It's really hilarious.
My favorite is Channel Chasers. I think that is the name. Timmy makes that remote control that can take him into any tv show/cartoon. I love when he goes into the Peanuts cartoon. Also the one where Timmy and Jimmy Neutron switch places. The Timmy/Jimmy TV Hour.
