Hank Williams, Jr. has often shown during his legendary career that he's not afraid to ruffle someone's Wranglers. His most famous bout came in 2011, when he compared President Obama to Hitler during an interview with Fox News. The comments got him fired as the theme writer for 'Monday Night Football' on ESPN. He responded with an accusatory song. Things eventually died down, and we all got a laugh out of it when he surprised Carrie Underwood and Brad Paisley at the 2011 CMA Awards.
