Jennifer Aniston was on with Jay Leno yesterday, and even though she was supposed to be promoting He's Just Not That Into You, it seemed clear that she doesn't follow any of the advice:

"I didn't know it was a book," Jen admitted. And when Jay read some chapters titles, like, "He's Just Not That Into You If He's Not Asking You Out," Jen said,"I don't agree with that… Aren't men shy? Sometimes?" As for "He's Just Not That Into You If He's Not Calling You," Jen seemed confused. "For how long? I don't know… I disagree with that too." Suddenly, it became very easy to picture her in a dysfunctional relationship with John "The Player" Mayer. Clip above.
