Sketch Empire comedians joined up with the team from KHA Entertainment to scare the crap out of hapless citizens in Columbus, Ohio.
The resulting "Jurassic Prank," featuring Sketch Empire's Roman Atwood and KHA Entertainment's Kojo the Tyrannosaurus rex, has received more than 50,000 views on YouTube.
The very realistic-looking beast elicits screams of terror from people on the street, homeowners and even an unsuspecting pooch.
KHA Entertainment claims to have one of the few professional-grade animatronic dinosaur costumes available to rent out in the U.S.
According to the website:
Kojo was custom built to look, feel and sound like a real, living animal! The articulation points, movable limbs and jaw, blinking eyelids and life like sound system all help sell the experience.
The "Jurrasic Prank" is very similar to a stunt pulled in Melbourne, Australia, a few years ago, in which an Utahraptor -- a larger cousin of the more popular Velociraptor -- was sent to a Melbourne mall to promote the traveling show "Walking with Dinosaurs," according to MSN.
