We love Dirty Jobs, Myth Busters, Man vs Wild, etc. here too!!! I get a huge kick out of the guy on Dirty Jobs.

My kids used to love Cyberchase but they don't care to watch it any more. It is a great show for younger kids though. They like Boomerang (not educational in the LEAST I'm ashamed to say) and all the old cartoons. It is interesting how much classical music they used in the old cartoons like Tom and Jerry. We went to the symphony and they played a piece of music (I can't remember what) and DS6 said "that's from Tom and Jerry!" I thought that was funny - but at least he recognized it I suppose. Maybe that could be considered educational??? LOL!!!

Magic School Bus is still one of MY favorites though they have seen them all and don't watch it any more. I just love how science is made fun. Someone mentioned brainpop.com and I agree that is really cool. Our school has a subscription but I believe there is a free area you can try out.
