It's more that short posts that consist entirely of cultural references for the purpose of making a joke are downvoted.

Generally.

That's the thing - my karma is high enough that I know what not to post. Generally speaking. Every once in a while though, I get tired of pretending that I don't also have a goofy sense of humor and stuff like this slips through. Oh well.

Humor is risky, sometimes it will flop, sometimes it will be greatly appreciated.

I think you need to do a little more than just plug cultural references, though.
