After I installed the rocket launcher and successfully used for self-defense office, several colleagues had the same and buy one. Well, after my home-made defense system did not help more, I decided to use a little sharper ammunition (sharpened) to better effect in the hits to land. Unfortunately, my colleagues also came quickly to interesting ideas - various firecrackers from last Sylversterfest caused hit on people and workplace Finally I remember vaguely that was handled with various hydrogen-combinations. Then at some point the lights went out. Oddly shows Google (I Wi-Fi in the hospital) only a crater at the place where once stood our company. From the annoying colleagues I have not heard at last peace !!!
