Jennifer Aniston may play one of titular crappy bosses in the movie "Horrible Bosses." But until she made it big on "Friends," she could have been more accurately described as a "horrible employee." In the press scramble for the movie, several reporters have asked her about her worst jobs and she's given a few different answers. "I waited a lot of tables, and I wasn't very good at that," she told Marie Claire. "I dropped more than one Alpine burger in customers' laps, and you just do not want all of that Swiss cheese and mushrooms in your pants." She also wasn't so hot at bike messengering—a profession I associate much more with tattooed guys than with America's Sweetheart. "The toughest job I had was being a bike messenger in New York City," Jennifer shared with Canwest News Service. "I was 19. [My lowest moment was] probably driving into a door that opened. I'm very uncoordinated and extraordinarily klutzy." [Showbiz Spy, USA Today]
