The review that this website has given portrays the movie as a funny, mild PG-13 movie. While it is indeed funny, the movie is far from mild.
The sexual content in this movie is simply excessive. All it truly needed was some more nudity for it to be R. There is constant talk about sex, references to "BJ's", "prostitutes", and "Hookers." The sexual humor is very explicit- in one scene, a women asks another man to "roleplay" with her and pretend to "spank" her. She is heard to be making groaning noises and calls her herself "a naughty schoolgirl." This same lady, in a later scene, claims that she "is wet."
Additionally, a man claims he loses his wife's "clitoris." This conversation continues for 10-15 seconds.
There is a scene where a man is found with two near naked women (leaves cover their private parts), posing erotically.
This movie is simply not a family movie- the sexual references make the whole experience awkward. Watch the movie by yourself before letting your kids watch it.
