Hats off to the wig wrangler on this one. Kate McKinnon’s Ellen DeGeneres impression approached terrifying Hitchcockian doppelgänger levels today when McKinnon stopped by to give the Ellen monologue. “That was you!” DeGeneres protested afterward, but it’s too late. The audience’s belief in the identity of the real Ellen has been shaken to its core, even their belief that such a thing could ever be known. Maybe I’m Ellen, they wonder. Maybe we’re all Ellen. Honestly, everyone would be totally fine with that, right?
