Two brothers played a mean prank on hotel staff - by making their room pillows and duvets look like DEAD BODIES. Gregers Federspiel, 17, and his brother William, 19, were staying at the Stracta Hotel during their holiday in Iceland when they decided to leave a present for the cleaners. The jokers used their room's pillows and duvets to fashion what appears to be a corpse wrapped in bedding at first glance. They topped off their evil creation by wrapping wire around the supposed head of the body - to make it even more the realistic. Gregers, from Copenhagen, Denmark, said: "We always like to joke around and prank each other- but this time worked together. "One commenter said the room could have taken hours to clean as staff may have to call the authorities - we hope that wasn't the case! "Hopefully we didn't scare anybody to much." The video was filmed on July 16.
