How Come Pens Like Playing Hide n Seek?

DNW is just wondering how come you can never find a pen when you need one real bad BUT when you dont, there are like 12 of them lying round at the bottom of your bag?

I am thinking there is a planet out there somewhere, far far away where the Alien - Pen and his alien wife Pencil live and plan how to drive me bonkers everytime I got to the bank and need to sign somthing. Am just wondering....do I need to chain a pen to all my bags? lol? And dont get me started on the why the printer always breaks down when I need to print something urgent. Its a war against humans I tell you!
