Throughout the series, Austin makes sexual jokes that kids most likely won't get
Mentions that the Great Fairy in Twilight Princess is topless and "that's pretty cool"
In the episode "Top 10 Mario Games", Austin mentions how, in Super Mario RPG, there's a female boss who's breasts jiggle every time you attack her and then states that this is more offensive than Dragon's Crown while a picture of a woman with large breasts appears (and I agree)

Some of the games he "reviews" contain violence and even blood/gore. In one episode, he has his character in Skyrim literally murder people, even children
Profanity

He also says, "screw this, it, or you" And says "damn" once in "Top 10 Alien/UFO Easter Eggs in Video Games"
