If you're in a situation where you're given a choice between giving up your wallet or possibly being shot, you'd be better off to give up your wallet rather than trying to play Kung Fu Master. To ask such a question on a website such as this is a clear indication you don't have the proper training to try such a technique (and even those who have such training will tell you that you're still better off not risking your life for the sake of keeping your wallet).
Yes
Yes as long as you are trying to take someone elses gun away.
Not if you wash your hands. If you leave the blood on your hands I don't think you will get infected.
with your hands just joking
They have clammy hands :]
Pick up someones gun and kill them with it
Generally speaking, no. Regardless of all the hype you hear, a gun shot will not actually separate a person's head from the body.
You can be someones friend by telling funny stories you also can shake hands or you can by game and give it to her.
you can but it is ilegle
Someones lap.
Only place your hands in or near someones mouth if you would like to be bitten. If someone is having a panic attack you should just help them sit or lie down in a relaxing quiet place.
Some gun shops, especially those with shooting ranges, will take them off your hands and dispose of them safely.
