So there's this cheeky colleague of mine, who, ever since learning that I'm a wuss when it comes to horror movies, has been pranking me with late-night fright-fest movie clips and links to anything scary or supernatural.

This has been going on for a few weeks now and yesterday, after another restless night thanks to my devilish work buddy, the seed of a payback plan started to form.

He's a delightful fellow, although his music taste can fall to the cheesy side.

So I photocopied a few dozen images of the cheesiest pop star I could think of and .... bingo, what do you think of his workstation's new Justin Bieber wallpaper?

My colleague starts slightly earlier than me each day, so he leaves earlier too.  I made use of that time late in the day to decorate his desk, chair, drawers and anywhere else I could find.

What do you think? I thought it was hilarious and was laughing the entire time, but it seems he wasn't a Belieber. When I arrived at work this morning all evidence was gone!

Are you a prankster? Or have you been pranked good?

I'd love to hear about it, since I feel I may have just started a war and could do with some great ideas. 

I'm not kidding, hahahaha, please help!
