This is a prank from Remi Gaillard featuring one of those realistic t-rex costumes, and one poor bastard who presumably thinks its an actual dinosaur or giant lizard. He gets so scared he jumps in a creek. Me? I would be running towards that t-rex, not away. But that’s just me, and I’m not afraid of anything. *email notification dings, jumps out of seat* What the f**k was that?!

Keep going for the video.
