superstitions...

[Danzig]

in light of the fact that it's friday the 13th, i thought i'd ask if anyone here is superstitious at all? black cats crossing your path make you inhale sharply? do you avoid the #13?-personally, i think it's silly that buildings don't have a 13th floor (doesn't that mean the 14th is REALLY the 13th???) and that airplanes don't have a row 13. i didn't consider myself to be superstitious at all, but then i remembered that i do indeed 'knock on wood' when appropriate!
so, anyone have a lucky pair of underwear that you wear to the track(or in drugs case, a lucky sock for appropriate occasions?!?!) ? or a rabbits paw on your keychain? how do you guys ward off evil?
