Getting her groove on with Jimmy, FROW-ing it up at Fashion Week with Anna and Karlie — seriously, how does Taylor Swift find the time? The pop star stopped by the Tonight Show on Tuesday to show off her comedic skills and slick dance moves. The set-up was this: Jimmy Fallon gave Tay grief for dancing everywhere because, once upon a time, that was their thing. The two were regulars on the NYC Fan Dance Cam, and the late-night host wanted to revisit their former glory. Cue a montage of a popcorn-munching, jersey-wearing Swift and Fallon busting into every dance move imaginable to the tunes of "Cotton-Eyed Joe," "Maniac," and other arena staples. The Robot, the Running Man, square-dancing, an homage to Flashdance... gotta say, their skills were on point. Kudos to Fallon for taking a bucket of water in the chest. Big ups to Swift for nailing the fish-on-a-hook wiggle. We'll keep an eye out next time we're cheering on the Rangers.
