There's a little person in my Dungeons & Dragons LARP guild named Balkazaar, and when I go out of town I pay him to dress up as a gnome and stand in front of my tower under my desk with his arms folded and a Viking helmet atop his head. When anybody tries logging onto MY computer without MY permission, Balkazaar pulls a Gandalf and says, "YOU SHALL NOT PASS," then goes medieval on their shins.
