Maru the Cat
"XKCD #676 mentions Maru the cat in its title text."
I want you to soak that in for a little while. Someone thought that a reference in the title text was notable enough to put a link into the wiki article. Or, more likely, the editor knew that it wasn't notable, but figured he could sneak one by on a minor article. We've got our eyes on you.
The reverter: "Every time your favorite comic mentions something you don't need to add it to wikipedia."
