well, i like the number of responses, I myself prefer the subtler aproach, the least offensive the better. And yes sometimes the "heckler" can add to a show but only if a performer has a good armoury of responses, to wit the thread. keep it up and maybe we ought to have a vote on our favourites! My favourite was the guy who sat with a heckler and asked how he should behave cos it was his first time. This also means trawling through the thread to find the good ones. A bit like singer/songwriters (oops I think I might get flak for that comment , joke - honest)
