One time in NY, I sat down on the subway next to a guy who looked pretty normal and he suddenly turned to me, whipped a Bic pen out of his jacket pocket, and said, "Do you know I could kill somebody with this?"
Fortunately, he didn't seem to have me in mind, and simply recounted various ways (nose, ear, etc.) he could kill with a Bic pen. The other passengers were fascinated and were all ready to run for their lives. I was a little freaked out, but I did get some useful tips...
He was right, too.
Just about *anything* can be used as an effective weapon.
Where there's a will to live, there's a way.
[my dad was a prison guard for 30 years. I know of ways to make weapons out of some of the craziest things]....LOL!
