I've read several books on writing and performing stand-up. I consider this the best.
A section I occasionally reread includes a list of eight standard joke forms. The authors explain that every comedian uses just one or two of the forms, retelling the same joke throughout their act. After reading that statement, I listened to several comedy albums and found it's true. Every comedian used one joke form repeated through the album. Carlin used Exaggeration, for example. Henny Youngman used the Reversal. This made me able to identify the form I'd been using and which I could refer to when writing for myself. It also made me aware to identify another comics' joke forms if writing for them.
A very practical book: Steve Allen uses stories of his own experiences to explain methods. In audience interviews, if an audience member spoke in an earnest, serious tone, Allen would make jokes. But if the interviewee tried to be funny, Allen would respond deadly serious.
After reading this book I wished I could meet Steve Allen and tell him how I enjoyed it and used it. One night, long ago, I was at a party he also attended and - there he was! I could have stepped up and told him but I got shy (introvert that I am) and didn't do it. I regret that now. I wonder if the co-author, Jane Wollman, is still around!
