3. The Random Foreign Object
This one is my all-time personal favorite.
The best thing about this particular weapon is that it could be anything, and come from anywhere at anytime.
I have personally used nothing but a Sharpie wrapped in black tape that I took out of my pocket, then replaced when I was done with my cheap shot.
Therein lies another great benefit of the foreign object, it can be as big, or as small, as you need it to be. Because of this, it can literally be hidden anywhere, and utilized whenever it's needed.
It's not used as much on on the level of WWE or TNA these days, but historically speaking it is a great weapon that is very dependable, and extremely effective.
