The Paper Clip Thieves

Okay, so today I am working away at my computer and out of the corner of my eye, I see a tiny flash of red by the white curtain hem.
On close inspection I see two more of those little guys and this time they are making off with a paper clip.
Well I know I don't always pick them up immediately when I drop them, but really that is no excuse to steal them!
By the time I had taken a quick photo of these two and put my camera down they had slipped behind the bookshelf.
They are pretty quick, I tell you!
