Great opening number on the Emmys just now: Jimmy Fallon, Tina Fey and Co. doing "Born to Run", managing to both celebrate and make fun of Glee at the same time.
And Jon Hamm gets to team up with Betty White. Or vice-versa.
ETA: another inspired musical number, Fallon doing "farewell songs" to shows that ended for good this season (Lost, etc) in the styles of EJ, Boyz2Men, Green Day.
