And yet, something like "American Pie" or "The Girl Next Door" that has actual nudity and other extreme things can EASILY get an R-Rating.
Why?
Politics.
"AP" and "TGNS" are mainstream movies intended for a mainstream, teen-to-20something audience and studios know that an R-Rating sends the "right" message that it may have raunchy sex jokes and nudity... But it's all in "good clean fun" since none of it should be taken seriously and actually falls within this countries twisted "family values" that we love to tout (yet we invade a foreign country for dubious reasons and our young men and women are dying for essentially nothing each and every day).
It's ridiculous, insulting and just another indicator of how hypocritical the system is in that if you have the money, you can buy whatever rating you want.
