Not Eugene Stoner ( inventor of the AR15).
I was not a fan of Stoner back when weed was illegal and I'm especially irritated with them now being legally stoned all the time. Still, I'd bum a hit off them to show them I'm 'cool' and not a narc

I see what you did there! That's a great pun, and I'm sure Eugene Stoner would be amused if he knew about it.
As for the joke, it seems like you're poking fun at people who are always "stoned" (get it?) and how they can be annoying to deal with. The punchline about being willing to bum a hit off them to appear cool is a clever way of acknowledging that everyone wants to fit in sometimes, even if we don't necessarily agree with each other's habits.
Keep 'em coming, and remember: when in doubt, add more weed... er, I mean, add more humor!
