Countdown with Ben Affleck

OK, so John McCain may have stolen the show the other night on SNL, but Ben Affleck was surprisingly good as well. Take a look at this lengthy lampooning of MSNBC's Keith Olbermann - he gets a little tripped up with the speed and intensity at times, but all things considered, this is about as good an impersonation as you'll see on SNL (not counting Tina Fey, of course).
