Adorable, lovable, and apparently scareable Chris Pratt is caught off guard with this Jurassic sized prank. Remember the man behind this awesome spider-dog prank well, he’s at it again, but this time with massive human dino puppets. You have to see how they pulled this off (after the break), and then how Pratt reacted after the fact. I’m pretty sure I would have soiled myself while screaming and judo chopping the hell out of everything around me. Fight or flight people, fight or flight.
