Jennifer Aniston may have had a lot ups and downs over the years, but stalking people was never a problem of hers in the past!  Yes, I said stalking, but not in real life-Jennifer is playing the guest role of a "Fatal Attraction-type stalker" on NBC sitcom 30 Rock. 

Jen will cameo as Claire Harper, the former roommate of Liz Lemon (Tina Fey) and now stalker to Jack Donaghy (Alec Baldwin).  There's also been some talk of a mock rendition of the Friends opening credits, ya know, splashing around the fountain and such.

I think it will be nice to see Jen make a return to sitcoms, even if for only one episode, it's the medium that made her famous! (And who knows, maybe she'll get a spin off!)
