Once I have an initial idea/scenario I ask myself “If this idea/scenario is 100% true, then what else could be true/real in this world?”
Here’s a deconstruction of one of my far from perfect jokes as an example,
Main Idea: I farted myself awake last night.
If I can fart myself awake, what else could my farts do?
Put me to sleep, make me drunk, make me better looking.
Who do girls think is good looking?
Jacob from Twilight.
If I fart myself into him what else could I do?
I could fart myself into a werewolf.
How would being a werewolf affect me?
Being bald, that would be great for me, because I’d have hair. Or on the other side of the coin, it would be bad, because if I’m bald now, I’d probably end up being a bald werewolf.
The variations are infinite. Use each thought as a springboard to another thought. It’s just like the verbal pattern game played in Improv.
Pattern game where word association is used to generate ideas, often referred to as a clover leaf because the pattern arcs out with associated words and returns to the suggestion, and is repeated two additional times.
With the fart joke I started with a main idea based in reality, then I looped out into the craziness of farting myself into a werewolf, then brought it back and grounded the joke with how this insane idea would actually affect the real me.
That said, I’m a novice and I still have a ton of exploration to do in terms of crafting a joke. When writing 90% of my jokes I didn’t use this technique. I guarantee though, if I go back and rewrite them with the pattern game in mind they will get 200% better.
P.S. It also helps to share jokes with your friends, sometimes they will spark an idea or offer one that makes a joke even stronger!
