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.Here is a Try Not To Laugh challenge with lots of giggle inducing clips. Unless you just don't like to laugh, it will be tough to sit through this entire video without wanting to snicker. So unless you're Scrooge, this should make you chuckle, guffaw, snort, and just split your side with laughter.
