The characters go to a hot spring in one episode. The (non-detailed) breasts and buttocks of various female characters can be seen.

One episode has a plot about a sex offender who glues girls' hair into ponytails.

While speaking as a profane drill instructor, a character makes some (partially bleeped) crude sexual remarks. He tells a group of boys to think of their rugby balls as 'a wet c**t and f**k it as hard you can'.

The majority of the show features only mild comic violence/weapon use and explosions, associated with the main character's military past.

Quite strong for a TV-PG, including frequent use of mild language like 'damn', 'hell', 'ass' and 'bastard', as well as occasional use of stronger words like 'shit', 'bitch', and 'douchebag'.

One episode has a character comically speaking like a profane drill instructor. Strong language is partially bleeped ('f**k', 'c**t', 'c**ksucker'), but the words can clearly be made out.

Despite the TV-PG rating on the official discs, there is a great deal of profanity, fanservice, and risque humor in this series that may make it unsuitable for young children.
