Hecklers are usually just drunk and almost never outshine the artist. It's the measure of a class act if they can not just survive a heckler, but get everyone on side against him/her (OK ladies, fair is fair, I've not ever even heard of a female heckler, but equality is what it is!)
wait,...did i even have a point?
