How do you deal with Hecklers

I know what I, as a magician and comedian, would do to deal with hecklers.
As a fire performer, although it rarely happens, I'm not as sure.
Thus I post this question to everyone: How do you deal with Hecklers at a fire performance?

I've never had this happen before, but I would just ignore them. I wouldn't want to ruin my show by having to speak out or stop fire dancing just to confront a heckler. Honestly, I think a heckler at a fire dancing show would get dealt with by the audience itself. Most people like fire performance. I think if someone yelled something immature like "you suck!" in the middle of a performance, other members of the audience would probably tell him/her to shut up. I know I would.

Me personally I either ignore them they are stupid to heckle and not worth my time to reply

Blow em a kiss

Or get the sound guy to turn up the bass

I chop them up and bury them in the woods...no body no problem...
Wait, did you mean ON stage? erm something legal, something legal!

*cough cough, points over there and walks in a different direction*

If they are in a group of friends, you can include the friends in conversations or as assistants, and talk ABOUT the heckler but not directly to them. Quickly, they will quieten down or start arguing with their friends, and not be directed at you the whole time.

Don't insult them or antogonise them directly. Be nice to them, constantly belittle yourself and agree with every disparaging comment and let the rest of the crowd manage them, and pump you up.

Often, I like to tell the crowd a loud 'secret'. It's ok, he's actually my wife dressed up, like the opposite of Mrs Doubtfire. She's here to stop me flirting...

Lot's of different ways to handle them...
