Contagious Yawning at the Heart of a Clever YouTube Prank [VIDEO]

I had a great uncle who was a biology professor and I asked him one time why yawning is so contagious. He said something about yawning having to do with a lack of oxygen but couldn’t exactly pinpoint why it was necessarily contagious.

He wasn’t sure, to be perfectly honest.

The Library of Congress contains psychologist Gordon Gallup’s definition of “contagious yawning.” He says it’s the “primitive empathic mechanism related to mental state attribution.”

Okay…whatever.

ANYway…

Enough science. Let’s take a look at a clever prank that was played on folks all over the world AND all of us who watch this YouTube video. Gotta be honest. The video made me yawn and so did THINKING about the video just now. So bizarre.
