NBC half-hour "Up All Night" has exchanged its third and fourth segments.

I think 30 Rock did the same thing with its 3rd and 4th episodes, probably just means the 4th episode is a little stronger than the 3rd, and for a show that is showing some ratings promise for a rather dire network they want to put out the best impression they can with the show.

I dont think its a problem. Unless, something happens in episode 3 and they talk about in episode 4 before episode 3 airs. NBC wouldnt be that stupid??Would they??:lol: ;)
