Megan Fox's character, Prudence, in Two And A Half Men is explained in this article. The sitcom debuted in 2003 and became a hit, but faced issues behind the scenes. Charlie Sheen left the series after season 8 and was replaced by Ashton Kutcher. Co-star Angus T. Jones also left after season 10. Megan Fox played Prudence in a 2004 episode, where she was dressed in skimpy outfits and portrayed as a sex object, which is uncomfortable in hindsight considering she was only 17 at the time. Fox has since been given better roles in movies.
