What's Going on in That Joke?

I'm actually almost against aha moments. Like, I think that they're way, way overvalued. The way I think of them is like a joke or a punchline of a joke. What's going on in that joke might not be very funny, but it's the meaning of the word early changes. So, you've built up this concept and then suddenly what happens is you switch to earlyness being not the age of the child at the time of day. That switch is like a new bridge that's being built between two things which separately were divided. And one thing was separately not involved, previously not involved.
