Last night I was assisting an older gentleman in the bookstore locate a book. He must have been in the range of 85 or so, and looked pretty worn out. After completing his order, he began to walk away and then turned back to me. He said, "When I came in, the alarm went off. I don't know why, I didn't have anything on me and I hadn't bought anything yet."

I responded to him jokingly, "Don't worry about it, that thing goes off all the time. It starts beeping every time I walk through because of the metal plate in my head."

He nodded and then a look of realization came across his face. In a totally serious tone he says, "Oh, really? That must be it then, I have one too!" Thinking that he is pulling my chain, I started to chuckle at his joke, at which point he turns his head, to SHOW ME THE SCAR!!! I was floored. I mumbled something to him in response and kept quiet until he left. Then the next customer stepped up to the desk and I asked her if she thought he was serious and she agreed that he was. We laughed for about 2 minutes before I could get it together to help her out. Man, being a wiseass is a dangerous thing.
