Simpsons in HD!

I went to watch some of my recorded shows from the weekend and was surprised (and a little miffed I didn't record it on an HD channel) that The Simpsons has now gone to an HD format. When watching I could tell it was clearer and that I was missing out on the whole picture. I can't wait to see what it looks like next week with my recorder now poised to get an HD recording... I guess I could try to watch it on HULU.com but oh well...
