OK, Nick has had a lot of great successes, like Avatar, Spongebob, Fairly Odd Parents, etc., and a lot of failures, like The Mighty Bee, Fanboy and Chum Chum, and the new seasons of Spongebob. But, I watched a new show today, and to my surprise, it was actually good.
TUFF Puppy, watch it. The show is funny, but not too childish. It's a good balance.
