Former Saturday Night Live writer Al Franken took some time away from his Minnesota Senate campaign to brainstorm last night's opening SNL skit with show overlord Lorne Michaels. The bit would have had whiny Wingers complaining that NBC is a bunch of lefty pinkos anyway-since it features McCain recording his approval for campaign ads that accuse Barack Obama of supporting "tax cuts for pedophiles," health care for Osama Bin Laden, and "fathering two black babies." But now that Franken has been outed as the original author of the piece, they're really going to poop their frightened pants. The Franken campaign is downplaying the candidate's involvement, but an SNL insider tells Politico that Franken's name was on the script alongside head writer Seth Meyers as late as Wednesday.
