As far as pranks go, this one is a tyrannosaurus-sized success.
In this Japanese video, a man is heading into his office for what appears to be another ho-hum day when, all of the sudden, he sees his co-workers fleeing from what looks like a dinosaur. The frightened man tries to hightail it out of there, not realizing the dinosaur is actually a puppet (note the human feet commandeering the costume).
It’s hilarious and kind of makes us wish the countless hidden camera pranks on YouTube make a dedicated effort to up their game. C’mon, USA!
