Challenge yourself and try not to laugh or smile during this entire four minute long video. I don't know what it is about laughing, but it is so easy to catch, much like a social disease. Or like yawning. But seriously, try not to laugh, giggle, or chortle. And if you do not chuckle once during this video, I will mail you five hundred dollars. Of course, you'll have to mail me a self-addressed stamped envelope first. Come on! Try not to laugh at the video of that cute giggly baby.
