I'm posting this video, in part, as a dare. I DARE you to watch the entire video and not yawn. I couldn't do it! I yawned twice while watching it...and then laughed at myself. It's truly the most contagious prank ever!

I have two favorites in this video. One, which will be no surprise to anyone who knows me, involves a dog. The other involves two guys who totally bust the star of the video for walking around trying to make people yawn!

So here's the challenge...watch the video...and then tell us...did you yawn? I'm betting you will! (I yawned again while typing this!)
