Priceless moment son tells dad he'll be a grandfather

This guy wants to tell his parents they are going to become grandparents.

But, he wants to play a little game with them in which they have to figure out what he is saying.

So, he makes them wear headphones, cancelling out his voice, and forces them to lip-read the news.

Granny-to-be is really good and gets it pretty much immediately.

Grandpa-to-be is not very good at this game. He just doesn't get it.

But, just wait until he does get it.

That moment is priceless.
