If you have never attended a presentation that includes a live coding session, one might find parallels in improv comedy.<p>Not all rehearsed comics, who assemble written jokes beforehand, and tell them as part of a routine, can be nearly as entertaining during an improv show.  Watching a UCB or ComedySportz or Second City live show, or Whose Line Is it Anyway is very different from watching an episode of The Daily Show or Saturday Night Live.<p>While good improv comedians can usually do rehearsed shows, it is much harder to go the other way around.  So unless you do a lot of live coding--perhaps you teach a university class that requires it--you probably shouldn&#x27;t inflict it upon a big audience until <i>after</i> you know you can do it without boring everyone to death.
