IF you thought you were a bad hotel guest for failing to wash up or make your bed then think again, a comedian has been leaving some "creepy" surprises behind that are designed to truly shock hotel staff.

A frequent traveller, funnyman Bert Kreischer has been giving hotel rooms around the world "disturbing" makeovers by leaving items behind or re-arranging them so that they appear to take on spooky forms.

Some of the creepy scenes by Mr Kreischer appear to show a man hiding underneath a food cart, a toilet transformed with fangs dripping with blood and a stuffed shirt inside a fridge.

In other rooms a sheet hangs out of a window like a rope and toilet paper is made into the outline of a body in a crime scene. Legs are seen poking out from underneath a bed, curtains and even from under a television mounted on a wall.

Mr Kreischer says his goal is to leave each room in a "semi-disturbing manner” – and he may well have succeeded if images of his creations posted on his Twitter page are anything to go by.

“I will pace a room with a pillow person in the bed, trying to figure out the best way to make the face ‘creepy’, but not ‘too creepy’,” Mr Kreischer said.

Mr Kreischer said that began the hotel pranks in a hotel in San Antonio, Texas in a bid to draw attention away from what he was really getting up to in his room.

“I realised that if a maid was insightful enough she could tell exactly what I had done in my hotel room and she might think less of me,” he said.

“So I tried to throw her off my trail by putting an ironing board in the bathroom next to a pillow encrusted toilet…and that started it all.”

Mr Kreischer said that he has not seen how hotel staff react to his “creations” but that he makes sure he always compensates them for their trouble.

“I am long gone by the time anyone from the hotel sees my “art”, but I always leave a generous tip and never destroy anything or create anything that would be a hassle to put back together in a matter of seconds.”

So which hotels were the most fun to redecorate?

“Hyatts and Hiltons offer the most amount of stuff in the room for you to create with… Holiday Inns and Red Roof Ins a pretty bare bones and you end op having to go into your suit case for props, but mostly all the props are the same… which makes it tough to come up with new ones.”

Mr Kreischer is using the hotel hijinks pictures to draw attention to his new show Bert the Conqueror. He asked people to come up with “hilarious” captions for images of the pranks uploaded to the website.
