This guy had the BEST reaction when he found out he was going to be a grandfather

Alexa Goolsby used the Whisper Challenge to tell her parents that they were going to be grandparents. For those that don’t know, the Whisper Challenge is a game featured on Jimmy Fallon - you have to put on noise-cancelling headphones and then try to lip-read what the other player is saying.
Her mother gets it straight away but Alexa’s father gamely struggles to figure out what they are saying and when he finally gets it… well, check the reaction out for yourself.
How sweet was that?
