In one episode, a man looks at pornography on his child's computer.

Sexual innuendo, many references (including mentioning of condoms), sex is talked about very openly

In one episode Lily does a performance at the school talent show, and uses the song "Big Spender" which is about prostitution. All the while teenage boys are commenting on how they'd like to be in bed with her.

One episode involves the birds n' the bees.

In most of the flashbacks, there are sexual scenes, no open nudity, but we see many of the characters are naked under the sheets

Claudia was pregnant with Lily when she was 18 and her teenage pregnancy is brought up frequently throughout the series

Lily is thought to be pregnant at one point and her parents are frequently worried about her sex life.

The girls often wear tight clothing revealing cleavage.

Some slapstick violence throughout the series.

Bar fights and violent fights between men but no blood, just pushing and shoving.

Few uses of F-words (they are bleeped/silenced/removed).

Use of ass, damn, hell, bitch, bastard, and many other vulgarities.

Older teen characters get drunk at least once. One time they try pot, which the parents used years ago and still keep around the house as a memento.

There was an episode about Claudia going back to her habit of smoking cigarettes.

The adults are seen drinking alcohol, as the main characters own a bar

None, unless you count Brad screaming in the pilot episode.

The episode with teenagera playing Ouija may frighten some, especially when the main character burst through the door.

Most of the characters are extremely dramatic and people talk very animatedly/yell a lot.
