One very drunken night with friends we discovered that if you put a garden hose up to your ass, you can actually fill it up with water and then squirt it out with substantial force. Of course a discovery of this magnitude had to be put to good use, so off we went to our local fast food drive through - me with an ass full of water and a head full of booze. We pulled up, ordered some random shit, and slowly crept to the window. As we got there, I got ready and hung my ass from the back window. The next moments felt like slow motion but we moved fast. The poor drive thru lady didn't even have time to realize that she was about to get hit in the face with a jet blast of asswater. I let loose right as she turned and looked at us. To this day I feel kind of sorry for her. Her life is probably never the same since then.
