For those of you still unclear on the concept, John Rogers ("Mr. Leverage") explains:
I still have a lot of gut instinct left over from my stand-up days. You do not "reach common ground" with a heckler -- you destroy a heckler, or anyone else who threatens the fragile emotional suspension required in a successful stand-up show. Destroy them, or suffer the consequences. A thousand people's night will go wrong based on one person's selfishness or idiocy -- and your failure to control same on a split-second's notice.
That is all.
