Pranksters gave the poor man the fright of his life, cunningly setting up a situation where fellow office workers could be seen screaming and running.

Soon all is revealed as a full-sized raptor pokes his head around the corner and gives chase. It’s actually a man in jeans, but who in that situation is going to take the time to check twice?

It’s quite fortunate for the TV producers this poor man didn’t collapse from a heart attack whilst being chased by this gnashing giant lizard of doom. Could this be the best prank ever?
