I loved Arthur as a kid. And when I say "kid," I watched Arthur until I was 14, and probably still would watch it if I knew where to find it and when on T.V.
Anyway, good ol' Marc Brown, the creator of Arthur, did an episode on Asperger's Syndrome. One of my college professors even emailed me about it. I'm sure most of you have heard, but for those of you who haven't, I thought I'd link to the segment where they explain what Asperger's is. I thought they did a fabulous job!
For the full episode here is part 1 and part 2 (it's about 15 minutes long). It's worth your time!
