Laura's priceless comic book prank

Laura Tobin deserves an Oscar after fooling us all on this morning's show with a priceless prank that left our nerves, especially Richard Arnold's, in tatters!

As some of the world's best known superheroes descended on the GMB studio to mark the start of the capital's comic book festival, London Super Comic Convention, our cheeky weather expert decided to get in on the action.

Dressed for the part in white surgical gloves, Laura unveiled a rare collector's comic book, The Replicator, but what followed was a heart-stopping moment that the team, and certainly Richard Arnold, will never forget?

Watch the hilarious clip to see how it all played out!
