This proud papa was caught off-guard when his son handed him a key to the house they'd just toured together.

"You're giving me a key to your new house?" Charles Green asked his son, Michael.

Michael and his girlfriend, Bridgette, spent four months dragging Charles around to all the homes they were supposed to be looking at for themselves.

At the end of the search, in the final house where they each swooned for the big rooms, Michael handed his dad the keys to a new home.

"Every kid wants to buy his father a house," Michael said on the video.

"I don't deserve this," Charles said through tears.

"You deserve everything, Pop," Michael replied.

Green plays "Angry Grandpa" in a YouTube series that Michael directs.
