I was tiding up last night and found a pen my bro bought me a couple of Christmas's ago.
So what? it's no ordinary pen because if press the top and you get a nasty shock. So I fitted a new AAA battery and took it in to work this morning to see what happened:
1) I left it on someone's desk and sure enough they pressed the top.
2) The person above handed to someone else and told them what it did, so they pressed it to find out!
3) Some one else picked it up off my desk, knowing what happened above, then pressed it to see how sharp the shock was.
I think it's like when your Mother told you not to touch something because it was sharp or hot, a voice in your head told you to find out how sharp or hot it was.
Oh, I work in an office with intelegent people, or so I thought. It may be relevent, but all victims were blokes!
