In folklore, the silver bullet is supposed to be the only kind of bullet for firearms that is effective against a werewolf, witch, or other monsters. Sometimes (not always) the silver bullet is also inscribed with Christian religious symbolism, such as a cross or the initials "J.M.J" (Jesus, Mary, & Joseph).

Famous quotes containing the words silver and/or bullet:
“A black pall, you know, with a silver cross on it, or R.I.P.—requiescat in pace—you know. That seems to me the most beautiful expression—I like it much better than ‘He is a jolly good fellow,’ which is simply rowdy.”
—Thomas Mann (1875–1955)
“Literary gentlemen, editors, and critics think that they know how to write, because they have studied grammar and rhetoric; but they are egregiously mistaken. The art of composition is as simple as the discharge of a bullet from a rifle, and its masterpieces imply an infinitely greater force behind them.”
—Henry David Thoreau (1817–1862)
