In case you didn’t watch last night’s Saturday Night Live: Weekend Update Thursday (and why would you have? The past three weeks have Tina Fey–less slogs), Will Ferrell showed up to blow the dust off his W. impression before he brings it to Broadway in January, offering McCain his malignant endorsement and matching wits with a typically hysterical Fey-as-Palin. We suppose we should probably enjoy this while it lasts, because once this election is over, it’s all Laser Cats and MacGruber until 2012.
