Charles Green is someone that millions have watched on their computer screens, but they don't know him by that name. They know him as his internet persona "Angry Grandpa".

He's known for going crazy over the pranks that his son Michael pulls on him, but this may be the greatest prank of all. 

In the latest "Angry Grandpa" video, we watch as Charlie and his son Michael tour a home that Charlie believes his son and his girlfriend, Bridgette, are looking to buy together.

As they walk through the home, Charlie points out all of the things that he likes in the house including the wainscoting, giant closets, master bathroom, and kitchen.

Around the two minute mark, Michael drops that charade and lets his dad in on the secret - he and Bridgette had purchased the home for Charlie.

He first insists that he does not deserve the home and that Michael and Bridgette should keep it, then dissolves into sobs as he embraces his son.

It's really, really dusty in here.
