Using such modern techniques to start a flame war is crass and an immediate sign of surrender. With primative techniques, my favorite is friction by rubbing two witty comments together until you get a spark. Blow this spark into some tinder of minor misunderstanding or misinterpretation and POOF! instant flame. Of course with this method, it is vitally important to keep your sense of humor absolutely dry.......
