When I was in first grade my nun was 41. You wanna know who my first grade nun didn’t look like? Answer: Jennifer Aniston. I’m not quite sure why she’s hiding her Mexican jumping beans with that bikini top but, eh, to each is own. Or is it “to each his own?” Semantics. Jennifer Aniston headed down to Cabo San Lucas, Mexico to celebrate the big 4-1 with her husband friends like Courtney Cox, Sheryl Crow, and Gerard Butler. I, of course, imagine them all playing Trivia Pursuit Friends Anniversary Edition or Monopoly: The Friends Board Game or Candyland: Central Perk Land.
