Common Sense Note
Parents need to know that teens will probably want to tune in to this deadpan show based on Martin's personality (even though he's firmly in his 30s, he looks and acts like a straight-out-of-college emo kid) and occasional appearances on The Daily Show. That said, they'll be exposed to a healthy amount of salty language, some of which (like "s--t" and "faggot") is bleeped and some of which (like "tits" and "ass") isn't. There's also some sexual innuendo and more violence than you might expect, but even the bits involving blood are meant to be funny.
Some pointed sexual innuendo pops up, such as in a song involving a "horny teenager" ... and a sock. Other skits talk about the mechanics of sex, seduction, etc.
Comedic incidents include a verbal battle over a parking space that veers into violent territory, a character whose father was murdered, face slapping, animated rats that kill each other (revealing small amounts of blood), and smashing a car with a baseball bat.
Regular use of "ass," "crap," "hell," etc., plus bleeped words like "a--hole," "s--t," and "faggot." Other language includes terms like "nipple," "tits," and "explosive diarrhea."
The show sends some mixed messages. While it's positive for kids to see a young person steering his own show, they're also being exposed to cheeky humor that lacks real depth or meaning.
