There might be a post for this already, but here goes nothing...
I will be starting to do shows for an improv club soon, and I know a lot of people that attend those shows or anything in that scene like to heckle, so I'm wondering:
What are the most common heckles you get and what are your replies?

I know that's not the thing you want to hear, but the replies at heckles are really something personal.
I have a friend that uses some lines that fit him, but if I dare use them, I know it could be a bit shocking.
It's the same when you present a trick.

From experience, this question is not relevant, because when you will find yourself in some sh**ty situation, you will not be thinking about your thread on the Café.
But this situation has to be handled with class and/or humor so it goes well, but it has to make you think about it when you are alone afterwards.
That's the way you'll have replies that will come flawlessly AND suit your style and personnality.

Good luck on that, this is not something easy, but eventually you will get the habit of performing.

Hope it helps.
