There was a point to this story, but it has temporarily escaped the chronicler’s mind.

Our reading
An editorial interpretation.
The narrator admits that the story had a point which has now slipped away. That confession interrupts the expectation that a storyteller knows where the tale is going. The joke makes forgetting part of the story instead of quietly trying to hide it.
