HAMISH and Andy scared one of their co-workers so badly that she wet her pants.

In a hilarious prank, the radio stars got their hands on “the most expensive and most realistic dinosaur on the planet” and lured some unsuspecting co-workers down to the carpark

The unlucky staff members were, as Hamish put it, “obviously not expecting a dinosaur to be down there”.

In the video, the co-workers shriek, scream and squeal as the incredibly lifelike dinosaur lunges at them.

After the initial fright, one of the victims told the boys, “I wet my pants ... a little bit,” to which Hamish responded, “We’ve got a code yellow!”

The Jurassic Carpark prank was thanks to Jurassic World: The Exhibition.
