I was searching the widget library and found an evil overlord widget :
Rule 220: Whatever my one vulnerability is, I will fake a different one. For example, ordering all mirrors removed from the palace, screaming and flinching whenever someone accidentally holds up a mirror, etc. In the climax when the hero whips out a mirror and thrusts it at my face, my reaction will be "Hmm...I think I need a shave."
Rule 52: I will hire a team of board-certified architects and surveyors to examine my castle and inform me of any secret passages and abandoned tunnels that I might not know about
Rule 174: If I am dangling over a precipice and the hero reaches his hand down to me, I will not attempt to pull him down with me. I will allow him to rescue me, thank him properly, then return to the safety of my fortress and order his execution
Rule 50: My main computers will have their own special operating system that will be completely incompatible with standard IBM and Macintosh powerbooks
Rule 172: I will allow guards to operate under a flexible work schedule. That way if one is feeling sleepy, he can call for a replacement, punch out, take a nap, and come back refreshed and alert to finish out his shift
