I am REALLY superstitious about spiking the ball before the game is over. I've got a troll I want to run, but in the event that things blow up in my face, I'm holding off. I mean, I could just lie about everything and there'd be no way for anyone to check it, but since it would actually be true, it would bother me if my plan backfired--even if I could still pretend I was successful to my troll-ees.
On a related note, anyone who talks about good sportsmanship or being in a fair fight has never been in a gunfight or a war. Von Clausewitz argues for at least 2:1 odds and the Marine Corps likes 3:1 odds. The time my house got broken into, going after guns, the attic ladder was down, and they'd missed the PPK/S in the desk drawer, I went up the ladder intending to empty the clip into anything I might find up there, because they were armed with potentially a .45 or a .357 and I'm not fucking around with "FREEZE! DROP THE GUN!" when I've got a piddly .380 with a 7 shot clip.
