Air travel and weapons
I was always amazed that TSA would take my nail clippers or pocket knife. Then, when I’d get on the plane, the flight attendant would hand me a can of beer or soda or juice. A can I could empty then tear open to make a bladed weapon. And I have also, when flying, made certain to keep in my carry on bag a bar of soap and a pair of socks. You know, just in case some one gets a case of crazy or Sudden Jihad Syndrome. Put soap in sock, hit, repeat. Sure, it’s not whiz-bang tacticool but one smack upside the noggin and it’s coloring books for Christmas.
Apparently the geniuses at the American Journal of Forensic Medical Pathology figured out that there are weapons all over planes. Like Marko said: Your weapon is that squishy grey mass between your ears—everything else is just a tool.
Update: As The Duck points out in comments, that doesn’t count the various office supplies that are in the bag.
