There was an interesting little piece on the Guardian website by an Aussie standup today. She talks about a story she tells in her act - a true story - that she kind of cringes about now. It involves a heckling incident which really freaked her out and which actually scared her quite badly - she then built a section of her act around it and ended up with something very, very funny - but has since begun to think that by doing so she betrayed the seriousness of what happened and how it affected her at the time.

She does it so well though - it is a shocking story, particularly the responses of the audience at the time, but her telling of it is hilarious.
