This is one of a series of videos where some grandkids play video games with their grandpa. At first glance, that doesn't seem all that fun to watch right? You have to check this out because not only is their grandpa hilariously into it while playing, the man has a look of pure joy the whole time. It's just awesome. The guy makes some of the best noises I've ever heard.
For those wondering, I believe they were playing Halo and Call of Duty.
