Good one.. lol.. I tend to smile and be a bit of a flirt anyway. My Husband just smiles because he knows that it really helps me with audience control. I tend to find it Ironic. Most girls will watch a performance, and enjoy it. Most guys will want to know how it's done... i guess their ego is on the line...not all. But while my hubby may get less hecklers, the ones he gets are more vocal DURING the performance.
Me i do not get more hecklers, but I will get more guiys approaching me during a break, asking.." come on hun, you can tell me, How was it doene? I swear I won't say a word."
I Just smile at them and say.." really? I swore i wouldn't say a word either. I am so glad you understand... " Then i show my cute dimples
I think the best way as has been said to deal with it during a performance is just say.." Know what? maybe later, let me show you something else first..." and move on...
I don't do the same trick twice...ever. Rachel. Very Happy
What I would do is learn an effect that by it's very nature LOOKS as though you are showing it to them again. but that by it's construction is one effect.
Say after they ask a few times " let me see that again." perform Red Hot Mama, or Jazz Aces. Then say after the first phase of Jazz aces, or red Hot mama say " You know you've been a wonderful audience... Normally i do not do this... but just for you guys... I'll do it again."
Then go on with the routine... I find it REALLY makes something like Jazz Aces into a magical performance. They think you are doing something you did not really expect to do... repeat an effect... and just for them.
Intellectually, they may know deep down it's all one routine, but emotionally, they feel it is a repetition. I would do it close to the end of the routine though...do not want them thinking they can just demand you do things over and over anytime they feel like it.
Once is Entertainment. Twice is Education.
