Q: Why couldn’t the 12 year-old go to the pirate movie?
A: It was rated arrrrrgh!

Explanation: In the U. S. there is a system of rating movies:
Rated G= appropriate for all audiences (general public);
Rated PG= Parental Guidance suggested- some material not appropriate for children;
PG 13= Parents Strongly Cautioned- some material may be inappropriate for children under 13;
Rated R= Restricted- children under 17 require accompanying parent or guardian.

Therefore, 12 year-olds cannot go to a movie that is Rated R, or, as a pirate might say, “Arrrrrgh!”
