I absolutely love The Documental. Its insanity is just unmatched. I've heard there's quite a few additional seasons yet to be released in the west, which is exciting.

Have you ever seen Gaki no Tsukai? It's the host's main thing with a similar concept with his comedian friends, but it's a bit more linear. Unfortunately there's no official western releases of it and you have to watch fan subs, which aren't bad, but still would be nicer to see official support. Funnily enough, they're fully aware of their western fan subs and support.
