You should. It's theoretically aimed at little girls, but there are reasons that adults of both sexes are such huge fans. Most of those reasons boil down to "the show is just that awesome."

If you go here for episode names, and then look an episode up by title on YouTube, it'll probably be there. Hasbro has been really nice about not issuing DMCA notices -- it's almost as if they actually want people to watch the show!

"Dan Vs" is also a lot of fun.
