McKee: Heckling the performer is a long-standing tradition of stand-up comedy. The performers know this and learn to respond entertainingly. That's why it's unwise for comedy venues to prevent audience members from heckling.
Chapman: Heckling is only a long-standing tradition of comedy because it's tolerated. And it's usually only fun for the heckler. In most cases, heckling is just a distraction from the performance.
