Extremely strong and sometimes rather graphic sex references.

one of the main characters typically has only underwear on, however this is played for laughs

Brutal, gory and very bloody violence throughout although there is always a tone of dark comedy behind these acts.

One or two uses of fuck in an episode and other milder profanities.

Basically nothing

This show is graphic, very dark, crude and not for the light hearted but it's a really dark comedy so most of the time nothing is actually serious.
