One of Raja Sen's twitposts reminded me of this gem from a Woody Allen's standup: Years ago, my mother gave me a bullet...a bullet, and I put it in my breast pocket. Two years after that, I was walking down the street, when a berserk evangelist heaved a Gideon bible out a hotel room window, hitting me in the chest. Bible would have gone through my heart if it wasn't for the bullet.
If it made sense to you, remember, it was actually not meant to!
