Hidden Camera Video of a Grandfather Reaction

I've watched this video 5 times in the last 5 minutes.

A girl created this cute little pregnancy announcement on a wall for her parents.

Clearly her father has a reputation for "secret celebrations," because the daughter planted a hidden cam to catch him in the act.

OK...I don't want to tell you too much.  Just watch the video and see why it has over 1 million views.
