How do you write a great joke?

When writing new, great jokes, use structured techniques like the rule of three, and also observe everyday situations and behaviors. I start from funny situations I’ve experienced or ideas that come to mind. I often go back to a technique I learned where I create a diagram around a big subject. For example, I just got engaged—so I put “engaged” in the center, and then branch out to things like my mom’s reaction, what my fiancé wants, and how my friends reacted. I see myself as an observer of human behavior. I use the rule of three a lot, which is about saying two logical things and the third being something bizarre. For instance, I say I’m an actress and I play certain roles, and the third one is something unexpected and weird. That structure works well when you're starting out because you know when the laugh is coming.
