The world's most contagious prank

Yawning around the world

Roman Atwood is a bit of a prankster, so when he cut a video together around the world we were immediately excited. Let us introduce to you the world's most contagious prank.

Roman's been travelling around the world showing the power of the yawn. As he says: "What if I could pull a prank around the world, almost like a magic trick, a prank so sneaky nobody knows its happening.

"This is something we do every day, but today, I'm going to make you do it with the power of a yawn."

Outside of landmarks like the Eiffel Tower in Paris, the Colosseum in Rome, and the Great Pyramids in Egypt, Roman walks by tourists while stretching and yawning, causing them to do the same. He even gets hussled at one point. Let's just hope he took the time to actually enjoy all the places in the background of these clips and didn't just sleepily pass through!

With a following just short of 85,000 likes on Facebook, Roman has built up quite the following.

The question is, did you yawn?
