One of my earliest inventions. It's much like the classic "Kick Me" signs, but it eliminates anyone finding out that you put a sign on there back. What you do is put a "Kick Him" sign on your back, and stand next to the person you want kicked. I would like to make an infomercial about it one day, because I like coming up with something unnecessary that "eliminates the problem step" and what have you.
Fast forward to the future and I'm now selling a shirt with the sign already put onto it (through iron on or whatever shirt places do) from my website store at TheUsedMagician.com
