This was really funny. Yeah, I was able to understand what he was saying. Then again, he might not have been able to understand his fly being open. The animation was really good. While it's just one joke, it works so well. This guy sounds like Patrick Warburton.
The facial expressions work great. I just like clueless this guy is. It works well for its surroundings. It's fun to predict what he'll say next. You must have made some of those words up.
