It’s a normal day at the office when suddenly you hear people screaming and then see them running for their lives. A number of things might run through your mind, but you probably wouldn’t expect a T-Rex to turn the corner. That’s what happens when someone puts on a dinosaur costume to pull off the best prank ever!

These videos come from Japan, with the first victim being a man dressed in business attire going about his day before the big surprise. The second video is another man woman who gets quite a shock when the dinosaur turns the corner. At least s/he was kind enough to pick up a sign that got dropped, and the dino was sweet enough to return a dropped wig.

I must own this costume.
