Yeah to me it reads like an example of stupid genius. Like you're smart enough to be able to logically equate similarities between different things while trying to use Aristotelian logic to uncover a fundamental truth about something.

Oh in this case like you said, what makes the car go. And the idea is let's find other things that also have similarities with cars and see if we can figure out what makes the car go based off of these similarities, and in this specific case we're looking at windows and since cars go and they have Windows but houses don't go and they also have Windows then it can't be the windows that make the car go.

But it's definitely one of those things that would only be funny in context of somebody mentally reasoning through this in situ and coming to this conclusion by their own cognitive processes.

Of course, explaining a joke doesn't make it funny and if you have to explain a joke then it wasn't funny to begin with so yeah.

It's kind of like the time I told a female friend, that I wasn't dating, that, "if I didn't like the way she sucked my dick then she wouldn't like the way I ate her pussy". It made everybody laugh but none of you are going to find that funny.

It's one of those things that sounds really bad by itself but in the situation it was hilarious and it was good-natured and only mildly offensive at the time.
