SNL returns for it's 38th season this Saturday, Sept 15, 2012 with host Seth MacFarlane and musical guest Frank Ocean.
The election-themed "Weekend Update Thursday" will return for a couple of episodes as well.
Jay Pharoah is taking over impersonating Obama from Fred Armisen, which I personally think kinda sucks.
September 22nd: Joseph Gordon-Levitt w/ musical guest Mumford & Sons
October 6th: Daniel Craig w/ musical guest Muse
