Are you feeling like laughing?  Sometimes we just need a good laugh.  Well, jokes can certainly make us laugh.  But how about just listening to someone else laugh?  Believe it or not just listening to another person laugh can actually make you start laughing.

There is a YouTube video of a guy who is a volunteer on some comedy show.  The guy gets up there and starts laughing and just can't stop.  Before you know it, everyone is laughing and even the comedian can't stop.

I've heard the saying that laughing is contegeous and this video proves it.  Go see if you can watch it without laughing:
