If you have to write a dozen bad jokes to get one decent one, and you put in the time, work, and concentration and write 12 bad jokes every week, after a year you’ll have a killer 8 minutes. I say “write jokes” as opposed to “make up jokes” because I actually want you to write them down.
How many clubs did you throw behind your back before you could do back-crosses? Each dead-end joke idea, failed gag, and fully polished turd that doesn’t even get a chuckle when you try it onstage is just one drop on your way to creating a 5 club back-cross laugh. For a comedy juggler, 8 minutes of new material is way more valuable than back-crosses.
But I do know how to write two dozen jokes and then find out which ones are funny.
I don’t know how to sit down and write a funny joke.
If you do, it’ll help you separate the joke writing part of your job from the joke choosing, joke polishing, and joke editing parts of your job.
That separation makes it easier to write more bad jokes.
