Ah, that answers my question. I was familiar with the Smithsonian, and didn't really expect to find the meme there when I clicked on the link.
Katie did make it clear that it is the meme that is being circulated by email and other social media, and that the link to Smithonian was an afterthought courtsey of google, which is what i suspected, although your article goes into much more detail about how these memes come about.
