Principal Ava thought her colleagues hired a stripper for her.

Several references to strippers, but it is all extremely brief, not explicit, and easy to miss.

Ava shows her toes to the camera

Ava is kinda inappropriate throughout and makes inappropriate jokes.

The holiday episode is the most inappropriate in season 2 so far. It involves twerking and dancing suggestively, and some revealing outfits are seen in the back. Their is also drinking and mildly suggestive music playing too.

In the first episode, a kid pees on a rug in a classroom. We don't see anything, only hear urine.

A girl throws up only the aftermath is shown on her shirt and arm you don't see her throw up

In The "desking" Episode, Janine dramatically falls off a Desk onto the floor

There's a mild fight between kids in the "Fight" episode.

Many uses of "hell", "damn", and "ass" throughout the show. Some uses of "bitch", "freaking", and "crap."

A bunch of kids dance to Cardi B and the word "ass" is heard in episode 9.

Frequent used of religious profanity, "oh my God", "God", and "Jesus".

In season 2 "bitch" is used on some occasions.

"Fuck" and "Shit" is used in the show but is always bleeped while used.

Lots of B words and A words. (B!!ch, A$$)

People drink at a party in the holiday episode

Even though 98% of the show is comedy, there are a couple mildly deep parts and sad topics. Like family running away and bad family relationships.

Some fights between co-workers. A lot of it is comedic, but some last throughout the episode and have slightly intense climaxes.

Season 2 is actually more sad than the first one to be honest. Season 1 focuses on comedy and the teachers trying to make the school better and get along, and season 2 actually has some upsetting moments and is a lot different than the first season.
