McCain the salesman on 'SNL'

Today's meta-moment, brought to us by Tina Fey's evil twin "going rogue" on "Saturday Night Live" with a "Palin in 2012" t-shirt and from Sarah Palin herself advising the Emmy-winning comedian not to allow the now famous impersonation to get rusty.

"A little advice to Tina Fey. I want to make sure she’s holding on to that Sarah outfit. Because she’s gonna need it in the next four years."

Since the real Palin's been going rogue for some time, we'll assume she means four years from now. And we shudder.

But back to the comic relief (boy, we sure do need that).

What we'll forever refer to as The Sad Grandpa episode of "SNL," with the above cameo from John McCain and a later appearance on Weekend Update, worked ratings wonders for the fired up series. It was the second-highest rated show in more than a decade. The top-rated? Of course, Palin's appearance a few weeks back.
