The first part of the joke. This is what leads the audience to think that you’re going one way when you’re really going another.>Assumption
This is anything that the setup makes the audience expect. There can be a rich world created by the assumptions implied by your setup. Greg likes to call this world “The First Story” and the assumption you’re going to shatter “The Decoy Assumption.” I like to call Greg “Sugar-butt” and “The Hammer.”>Shatter
The thing the setup is revealed to really be about, the world implied or stated by the punch. I’m using the term “Shatter” for this part of a joke to match what I’ve written in my other articles. Some comics call this “The Turn.” Greg calls it “The Target Assumption” and the world created by it “The Second Story.”>Connector
This is the thing in your setup that is perceived in two ways, the thing that changes when the audience reinterprets your setup and realizes what’s really being said. Greg coined the term “Connector” for this part of a joke and that’s the term I now hear the most for it. I’ve also heard comics call this “The Pivot,” “The Link,” and “The Switch.”
The connector changes its meaning when the audience mentally moves from where they assumed you were going (the first story or decoy assumption implied by your setup) to being surprised by the shatter (the second story implied or stated by your punch). Greg calls this change “The Reinterpretation.”
Note: Connectors don’t have to be words. They can be phrases, gestures, objects, attitudes, ideas, purposes, or anything else that can be perceived in two ways.>Punch
This is the second part of the joke, the part the audience laughs at, the surprise that makes them reinterpret the connector, the thing that makes them infer the shatter. Also called the punch line.
