One man decided to give his father the gift of a lifetime, and lucky for us, it was all caught on tape.

This week, YouTube star Michael Green posted a video in which he surprises his dad, Charles, with a brand-new house. Charles is the inspiration behind Michael's "Angry Grandpa" YouTube series, where the elder Green hilariously and angrily reacts to all manner of situations from destroying a PlayStation [1] to eating a Whopper [2].

Anger wasn't present, though, when Michael and his girlfriend, Bridgette, shocked Charles with the house. Michael and Bridgette had been bringing Charles along on the hunt for a home that would ostensibly be for the younger Greens. In reality, though, the search was for Charles. And you won't believe his response when the secret is finally revealed. Get your tissues ready!
