Can anyone recommend any TV shows that are (legally) on YouTube?

I've watched Monday Monday on there. Really wish it got more series, but that Fay Ripley got a more solid character.

Alas, I can only watch it so many times before becoming bored of it.

Mystery Science Theater 3000

Start with Manos or Space Mutany.

Both Tenko and Colditz are on there. Well worth a watch.
