Months of sex with pop crooner John Mayer is enough to kill anyone's sense of humor, but Jennifer Aniston appears to have survived it tolerably if her 30 Rock guest spot is any indication. In tonight's episode Aniston plays an old friend of Liz Lemon who becomes an extremely clingy accessory to Alec Baldwin's Jack Donaghy. Of course, we can't help but connect the cameo with the real life Vogue cover story where Aniston lashed out at Angelina's poor manners. Since there's been some extremely unsourced talk about Aniston joining the series as a regular, so now is the time to figure out from these three hot preview clips if Desperate Jen is funnier as a character than she is in real life.This W photoset showed us what life is probably like in the Pitt-Jolie household, but we never got to be a fly on the wall in the early days. This month's Vogue cover story featuring Aniston takes us as far back as the beginnings of Brad's affair: "I felt those details were a little inappropriate to discuss. That stuff about how she couldn’t wait to get to work every day? That was really uncool." Amazingly in the same interview she relates her feelings about whining and complaining, with Vogue providing the emphasis:

"I don't…like…girls…whining…and complaining…about…wanting a man! I never liked Sex and the City, the kind of thing where women only feel empowered once they find the Man. It is just not up my alley. I don't believe in it. There is nothing you can control about love. Somebody once said, Everything you want in the world is just right outside your comfort zone. Everythingyoucouldpossiblywant!"

This more aggressive approach sounds eerily like Jen's courtship of Alec Baldwin in the episode. Oprah's cameo last week probably helped the show avoid the usual second-week dropoff, and interest in Aniston's return to TV is likely to do the same. As for Jen, a starlet is best judged in small doses.
