I perform what I call free-associational stand-up comedy at The Buttonwood Tree in Middletown, CT, every Monday night. A friend of mine who also is a comic, Basil Ali, posted a video of my performance on April 23, 2012 on YouTube. Here's a link to the performance if you want to see what I do in my act.
I always have some general idea of what I'm going to do, but I also use free-association from cues which occur during my performance. I also invite my audiences to interrupt me anytime, heckle me, try to throw me off-pace, or otherwise participate, and they do. I wish I could have at least a half-hour or more to do a full performance and really have enough time to get the audience even more involved than they were the night of this video.
Here's the link to the video, which is 7 minutes and 48 seconds long:
The reference I make to the weed wacker is based on what happened a few minutes earlier in the evening. Our hostess and emcee, J Cherry, was limping that night. She told the audience that that afternoon, she had been working in her garden and hurt her foot pretty badly while she was using a gasoline-powered weed wacker. As soon as I heard Jennifer mention a weed-wacker, I knew I'd be able to use that reference to comedic effect in my act. I've been asked to keep my act "clean," so I love it when terms like weed-wacker come up before I go on stage and I'm able to be "clean" but suggestive.
