I can't believe it - my bossed just pranked me!
I brought a document into his office for his signature. He looked for a pen. I saw one on the desk and handed it to him. He kept looking for a pen and said "Try that one. See if it works." I depressed the clicker and got a nifty little shock in my thumb!
He turned red laughing and appologizing at the same time.
That was too funny. I can't believe he did that! He said the pen's been on his desk for six months and no one had yet asked for a pen. Lucky me. =-)
