There's only so much cute a heart can handle, and the "Up" scenes involving Carl and Ellie were totally testing that limit because AWWWW. And now, thanks to a pair of grandparents who've been together for 60 years (!!), we know exactly where that breaking point lies -- right here.

This Grandma and Grandpa, the grandparents of pianist-slash-YouTuber Jason Lyle Black, came together to create an epically adorable tribute video of themselves sharing a tender moment together at their family's favorite instrument, playing the feely montage music from the movie and offering up subtle winks to the pic, like a "squirrel" reaction from their dog and a shot of the resident tennis ball-bottomed cane.

"My grandparents were very excited to be part of this video," Black said. "It was so fun to work with them on it. I've loved their piano duets ever since I was a little kid, so this will be a family treasure for all of us." Yes, ALL of us.
