Simply titled, "The Reveal to Grandpa," this sweet video will most likely leave you a little teary-eyed. Trust us, it's worth it.
YouTube user Jessica Hickey uploaded the video six days ago, and it's already garnered over 4 million clicks. Her dad's response to finding out he's going to be a grandpa is one of sheer joy and even moves the man to happy tears.
A user who claims to be Hickey posted the story to Reddit as well. She purportedly wrote that she is "his only child and my mother passed away 20 years ago. He has been asking us for grandchildren since our wedding night. I think he is happy. :)"
