Mostly sex references throughout seeral series, including some charachters still being virgins, and putting hands up a womans skirt, nothing is ever shown though, other than one character waking up next to an inflatable sex doll and the other next to a woman though nothing is shown to happen.

on the episode Time there is a skit of dallas at the beginning and in the images it very briefly shows a bare bum and several pairs of showgirls bare breasts however this is very short and not always easily noticed.

In episode Bambi, Vyvyan sticks his head out of a moving train and is decapitated. Lots of comical blood spurting, and Vyvyan's headless body finally finds his head on the tracks and reattached. May disturb some viewers.

Lots of comic violence throughout, in particular with the character Vyvyan who is a mad punk and Rick who is an anarchist. Neil constantly wants to kill himself and is constantly seen digging his own grave or with a noose around his neck.

The word, F#ck is not used throughout the series.

Occasional mild use, usually of the words "bloody", "bastard", "piss".

There are a few instances of racist language, including the word "nigger", but it is never direct or strong.

In the show's entire run, the word "Shit" is used only once, in Episode 3 (Boring).

Neil and some of his friends are shown smoking out of bongs, etc. They are clearly supposed to be smoking marijuana, as Neil floats off into out space.

Some smoking and drinking is shown.

Vyvvyan is shown drinking an unidentified blue liquid implied to be alcoholic that causes his hair to fall out in one episode.
