The Muppets
Home Movies (a cartoon from a few years back)
Talk Radio (Bob & Tom, Glenn Beck, and Dennis Miller mostly)
The News (I love the Drudge Report)
Disney
Anything from Tim & Eric, those guys are hilarious
Anything from Wiliams St. Studios (Space Ghost, Sealab 2021, etc)
...that's probably it for now. I know I'm leaving things off the list, but that'll get me started.
