Honestly, I wouldn’t have thought that something with that title could have been an Onion article. And to me that’s what “Not The Onion” is all about.

It doesn’t suffice that it’s simply a real article, it must make people wonder if it’s satire or not.

In your case, maybe if it was worded differently, but the way it is, it doesn’t make me think it could be something I confused for an Onion headline.
