I think it's pretty funny when taken as it was intended- comedy. A vast majority of the comments on youtube were from people who are either too easily offended, or just don't get the joke. I am sure that we all know a fellow brewer that likes to experiment with various odd things to add to their brews, and it ends up like bratwurst ale.
It didn't specifically say anything bad about homebrewers, it was just a charicature of a wacky dude.
Who knows? This just might pique the interest of some people enough to investigate and start brewing.
