Live from New York! Its Saturday Night! The SNL machine is something thats bigger than any one person. It's a condensed, stressful hell to get a live show on the air; the average guest host should just give him or herself over to the process. But Taylor Swift is no average guest host; Taylor Swift is one of the only hosts to write her own opening monologue.She delivered it in song, and she managed to call out both Joe Jonas and Kanye West while keeping a passive aggressive grin on her face. It was a classic SNL moment (those moments are ever harder to come by these days), and Taylor put her signature stamp on a timeworn, TV tradition.
