Good for you on the teletubby ban.
I watched the telestubbies for like 2 min with my son, and was like WTF is this?? the tubbies were all eating some pink crap that came from a faucet, and the smallest one keeps saying "more" and gettin more pink stuff. At that moment I forever banned the stubbies from my house. I don't want him being taught to keep saying "more" when he doesn't get as much as he wants. It's gotta be some kind of brain-control/indoctrination show for the kiddies. Ever read Brave New World? At least Sesame Street and Barney teach lessons and stuff like that. Even though I can't stand Barney.
The TTs serve no purpose but "entertainment", and that's mostly for stoners and acid/wig casualties.
