We've been hearing all about Jack's obsession with a former high school crush, played by Julianne Moore.  In our next episode we see how far Jack will go to end up in her path again.  This after he's already broken into her home and invaded every bit of privacy the woman had.  I'm not sure if we're supposed to be rooting for an obsession that's so obviously over the edge but leave it up to 30 Rock to present his behavior as normal.  Also in the upcoming episode, Liz takes the show on the road-litterally!
