This is actually what I consider a good children's Christian television show. It's by Art Clokey, the guy who did Gumby, and it's quiet, nice and unassuming, and for the most part, the lessons tend to boil down to "Don't be a jerk". Sure, there's a religious aspect to it, and a bit of a religious backing to the morals, but, hey, you know what? I'm more or less fine with that. It's the whole Not-Being-A-Jerk thing that's crucial with me.
