This hilarious comedy has a very good first season, but many inappropriate things happen. There is some strong language and they talk about periods. There is also a scene where two men wake up in bed together after being drunk and they are also nude but the sheets cover up everything apart from the chest.
In the second season a man suicides and another shoots himself in the leg, a man also tests if a gun is loaded by sticking it in his mouth and pulling the trigger. Also a man is gay and takes the main characters to a musical called "Gay".
In the third season they swear a lot and a man gets himself involved with criminals. There is also a man who tries to use rohypnol on a woman but ends up taking it himself and tries to have a sexual affair with another character, but fails. The character who is the chauvinist draws a picture of a woman with big boobs.
In the fourth season a masseuse kisses a man on the bum, also two people go to court for a divorce.
Overall there is really only one really bad inappropriate person but it really depends on your kid, I do think some teens should be fine with it, but for others it may not be very appropriate.
