Winnebago Man - Not family friendly!

This guy has me rolling in the aisles of my mini winni. Holy shit. Apparently he became a sensation when these outtakes from commercials in which he's the Winnebago spokesman surfaced on YouTube, and eventually someone even put together a documentary on him, called Winnebago Man. I haven't seen the documentary, but I'm thinking it just might be hilarious. Or sad, or hilariously sad. Or... well, you get the picture.
Goddammit.

PS. I really want to see the movie Duets. Has anyone seen it? Thumbs up? Thumbs down?
