Video: Taylor Swift and Fallon Dance It Out for Tonight Show Anniversary

Jimmy Fallon and Taylor Swift are maniacs, maniacs on the (stadium) floor.

On Tuesday’s Tonight Show Starring Jimmy Fallon, the platinum-selling recording artist and titular host revealed their secret past as frequent Jumbotron dance partners.

Despite the “unplanned” nature of their routines, the duo sure attended various sporting events equipped for wood-chopping punches and Flashdance-inspired set pieces, among other stunts.

The segment helped usher in Fallon’s one year anniversary as Tonight Show host. The hour also unveiled a follow-up to his oh-so-delicious Ben and Jerry’s ice cream.
