Megan Fox's character, Prudence, on Two And A Half Men is explained in this article. She appeared in the season 1 episode "Camel Filters and Pheromones" in 2004 before her breakthrough with Transformers. Prudence, portrayed by Fox, is only 16 years old but is constantly shown in skimpy outfits and performs seductive tasks. The uncomfortable nature of the character becomes apparent in hindsight as Fox herself was only 17 at the time. Prudence is portrayed as a sex object with little substance, but Fox has since been given better roles in other films.
