Learning you're going to become a grandparent just may be one of the happiest days of a person's life (at least that's what my own parents tell me). Unlike the fear of the unexpected that comes with finding out you're going to be a parent, grandparents have been there, done that and can now shower attention, love, and gifts on the next generation. And when it comes as a total surprise — and there's a camera there to catch the news — it's even better. Don't believe us? Just watch dad's reaction to see the purest display of happiness we have ever seen!

According to the mom-to-be who delivered the news, Jessica Hickey, the circumstances around the video only make it more touching. "Told my dad he is going to be a grandpa. I am 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."
