YouTube prankster Roman Atwood has recently traveled the world with his good friend Dennis Roady. They documented their travels on their Vlog channel

Over the trip, they made this unique subversive prank video that really borders on social experiment. From Egypt’s pyramids to Mount Rushmore, Roman walked around crowded areas yawning the biggest yawns he could muster to see if he could cause passersby to ‘catch’ the sleepy yawn bug. 

Could this be the World’s Most Contagious Prank?
