RV Salesman, Jack Rebney, Maddened!

This is possibly one of the funniest videos I've ever come across. Apparently, the video has been around since 1990, but today was the first time I've seen it. After a little research, I found out the guy's name is Jack Rebney, and these are outtakes from a informational video he and his crew were trying to shoot that day. This guy has an extremely short fuse!
