If you haven't seen it, check out the video of a guy in a Cubs jacket finding out he's about to become a grandfather. His daughter breaks the news by giving him a pacifier with a note tied to it that says her due date.
And first he's super excited, like a kid who just got the perfect Christmas present. Then within ten seconds, he's crying. (Search for "The Reveal to Grandpa." If you're curious, the note he starts reading at :17 says, "Hatching November 17th, 2014.")
