Maybe we're just terrible people or we're revealing a lot about ourselves here, but there's something about hidden camera pranks that makes us question whether people are in or not.
Let's take this one as an example. To begin with, if you were in a car for an hour and a half and bursting for a wee, would you be as calm as Cat Deeley? Not a chance. Next, if someone left a fish pie in a microwave in a dressing room, there's a good chance someone's going to die.
How about somebody using an aerosol thing repeatedly? OK, you know, people have different tolerances for that stuff, but still. To be fair to Cat Deeley, you could see her swallowing the rage during the Cbeebies part of the prank.
After a day like this, it's completely understandable.
Take a look.
