"Rated Aargh!" is the eighteenth episode of Lizzie McGuire.
Lizzie and her friends lie at their homes and sneak off to see an R-rated movie that everyone else at school has seen. While at the movie theater, Lizzie saves a man who is choking on a candy ball and gets interviewed by a TV crew. Lizzie's parents come to know of it and Lizzie gets busted. Meanwhile, Matt is having a fair at school and Jo decides to build a velcro-wall in which kids can jump onto.
