She's a Beauty, that Number 9

On the late-night editions of Sportscenter, one of the “anchors” (for lack of a better term), Neil Everett, has a tendency to say, when counting down the top plays of the day, “she’s a beauty, that number 9.”

It seems like I recognize that, but have NO idea where it comes from. I know the Tubes had a song called, “She’s a Beauty.” But it seems like his statement comes from some pop culture reference I should get, but don’t.

Anyone have any ideas?

ETA: A Google search didn’t help any.
