Some episodes have women in really short outfits and sometimes very snug on the tops which they focus on the breasts

At the end of each episode until the 4th season,when the credits are rolling,Oscar and Felix walk past a very obvious club awning that says topless and Oscar looks thru a window but nothing is shown

Some sexual references here and there. Nothing that bad.

Slapstick.

Infrequent mild language, occurs in some episodes. And even then, it's only tame words like hell and damn.

Oscar frequently smokes and drinks.
