Alexa Goolsby and her husband decided to break the great news to her parents that she was pregnant by making them do the whisper challenge during family game night. (The game involves participants wearing headphones with loud music on and then guessing what the other people are saying.)

It took her mom no time at all to realize what was going on, but dad was so invested in the excitement of the game that it took him a bit longer to crack the code. Watch his hilarious reaction once he catches on.

That’s pure happniess right there. I’m certain he’s going to be the best grandfather ever.
