Here's a question. How come nobody arbitrairily puts the plug on the other end and jumps on it? What decides which end of the pole becomes the end you grip once you get the pole in your hands? Couldn't you just lop the top off and put a new sticker on it? And yes, I've seen this done.
It only proves the theorum "What you don't know CAN hurt you".
I can't agree with Dub on this one. If the Indian Chief made the arrow poorly its the Chiefs fault. If the indian borrowed the arrow and messed with it before shooting himself in the foot with it, it's the indians fault.
This is the kind of thing that enables lawyers to live comfortably pretty easily. Sorry, I'll get off my soapbox now.
