Well, I don't know any channels, but if you go to youtube.com and search "Gaki no Tsukai" you will get TONS of episodes. It is basically a "torture" type game show run by this 5-man comedy duo. It is very hilarious and you don't need to understand what they are saying *most* of the time to have a laugh. My favorites are the games where they are placed in an every-day setting (such as a high school) and can't laugh or else they get spanked. Sounds kinda sadistic but it's really funny. Does that help? I know it's probably not what you were looking for but it might entertain you for the time being.
