Comedian Dave Chappelle said, "I actually write my jokes backward." He thinks of a random funny punchline, he writes it down on a piece of paper, puts it in a fishbowl and when inspiration strikes, he comes up with a funny story that 'lands' on that punchline.
For example, his punchline was, "And,... I Kicked Her in the Butt!" (Note: I've cleaned up the actual line)
Sometime later in the Netflix special, Chappelle ends a random story on that very punchline! Shocking the audience into laughter and demonstrating once again why he's one of the best comics today!
This got me to thinking about how we 'ask' for things; especially in selling. What if we try a Chappelle Close. Instead of trying to learn 101 clever closes, why not come up with one good 'closing line' and build a value story around it.
