I have this electric car. I thought it would take all the joy out of driving, but it doesn't, there are these mods I can do that make it really fun. I'm totally happy about it.

Then, at a campfire, I'm telling a joke about the electric car to some little boys. The pattern of the joke is like I'm going to get an electric car, but then something else is suggested, to distract from it. But then I completely forget where the joke was going, and sit there for a while pondering it, but I can't remember the punchline.
