Tons of sex jokes, made up sex scenes, flirting and more. ( Only in episodes revolving around couples), though sometimes also inserted in episodes not relevent to that subject.

Couple feet jokes.

There is quite a lot of strong violence in earlier episodes, not as much in recent episodes.

A lot of the violence is made with objects or hand slaps. Sometimes there are kicks, bat throwings and more.

Tons of fuck, shit and more.

Some episodes involve alcohol or any substances, but only cause it's the subject of the episodes. Otherwise, it's never shown.
