Charles Green thought he was helping his son Michael and Michael's partner Bridgette look for a house they could settle down in.
But the parent got the surprise of his life when Michael revealed he had purchased the house they were standing in for his father.
Charles, who is better known by his namesake Angry Grandpa, usually appears in YouTube videos where Michael pranks him. But the video above shows both men have a sensitive side.
"For the past few months, Bridgette and I have been planning a huge prank on Angry Grandpa and today's the day we're going to pull it off," Michael says at the start of the video.
As the group walk through the house room by room, Charles points out things that he likes and gives the "big rooms" a big thumbs up. Then Michael comes clean about his grand plan.
"We are searching for a house for you," he says as he pulls a key out of his pocket and hands it to his father. "This is yours."
Cue a very emotional father-son moment.

'80s Dads In All Their Dad-Bod Glory(38 of50)
Oops!(39 of50)
"In 1989 my dad (on the far right) grandfather (holding the ladder) and family friend were building a deck off the back of our house. After they got the first boards up my mother said 'looks nice, but how are you going to get the ladder out?' They forgot to move the ladder before securing the last board for the frame!! They ended up cutting the ladder apart to get it out. Also, notice the awkwardness of the jean shorts." (credit:Awkward Family Photos)
Who Wears Short Shorts?(40 of50)
"This is a photo of my dad back in '84 or '85. Those were one of his many pairs of daisy dukes. Both him and my grandpa had a matching pair of ones with rainbows on the sides. I was always embarrassed when they would attempt to take me out in public while they were wearing them.” (credit:Awkward Family Photos)
Breakfast Of Champions(41 of50)
"This was taken by my mother on Father’s Day 1986. My sister (far right) and I are less than thrilled to be missing morning cartoons. Not to mention our king-for-a-day dad obviously scored the only tray in the house so my eggs were precariously balanced on my lap. As for my sister’s cereal… that most likely ended up in the bed as well.” (credit:Awkward Family Photos)

And One From The '70s(50 of50)
“This is my father in about 1973 in the Central Wisconsin vacation town called Waupaca. We recently found it in the attic when down-sizing my mother’s home. Yes, he is wearing shorts, but I don’t know why he chose to wear the hat with all that pasty white flesh bared to the elements. The picture is complete with the Frisbee in one hand and the can of Old Milwaukee in the other. Though Dad has been gone for many years now, his sense of 'Every-dadness' lives on in this priceless photo.” (credit:Awkward Family Photos)
