If you're a parent doing the Elf on the Shelf craze then you might just be getting a bit sick of the cheeky blighter by now.
It all starts off as some harmless family fun and usually ends up in marital rows as couples argue over whose turn it is to move the elf tonight.
If you don't already know, the Elf on the Shelf craze started in America, but has become somewhat of a tradition in the UK.
While many families use the official Elf on the Shelf merchandise, there are many other versions available from pound shops and the like, so it's a trend that's become accessible to all.
The idea is that the elf has been sent to spy on children and report their behaviour back to Santa.
And to prove it's real, once kids are safely tucked up in bed, mums and dads put the elf in different locations in the house so he pops up somewhere new when they wake up in the morning - usually having been up to mischief during the night.
But while most parents have been sharing photos of the cheeky antics of their little guests, others have been taking it up a gear - with some 'adult' Elf on the Shelf ideas.
And while some are pretty mild - pooing on the window sill, peeing in the sink and photocopying their bare bottoms - others are frankly pretty shocking.
Among the photos shared on our MEN and Manchester Family Facebook pages are two planetariums offering free views of Uranus - and we don't mean the planet - an elf performing a little surgery on a Barbie doll, and plenty of other compromising positions.
See some of the ones we've received in our gallery (we've received much more graphic ones than those featured here) - it might be advisable to avoid it if you'd rather give such filthy shenanigans a miss:

And for more inspiration you can see the cheat sheet that's doing the rounds.
Put together by Country Living , it lists a whole host of activities to keep the elf busy over advent, including leaving children a Christmas message made from candy, eating cheese in the fridge and even sitting in the car with his seatbelt on.
