More about camel walnuts.
Your going to need the following:
- a slingshot
- hot pepper
- water balloon
Now... mix together the hot pepper and mace inside the water balloon and have a friend shot the balloon at your face.
(Also, now you realize that your friend is a prick for not caring about your well being and doesn't mind shooting you in the face with a fucking shit bomb of WTF! Then kick that prick in the dick and call it a day.)
