I'm sure most here have seen it, it's been repeated many times. The Regular punch is in bar fights and other lengthy fisticuffs were guys pummel each other for 5 or ten minutes before finally wearing out, 20 blows or more. The Secret punch is one and out: guy turns around to the guy waiting for him, catches one in the face and goes down. Gets carried out, water on the face (or beer) to revive him from 1 (one) punch. Or he might stay down until everybody is gone, long time. Does anybody know the key to the Secret Punch, why it's so devastating and how to deliver one?
