Jack frequently discusses his sexual exploits with his students.

Frequent mild to moderate innuendos and references.

Some kissing.

Jack is seen sitting naked in his shower, his full torso and legs are shown. No genitals are shown, they are covered by a wash cloth but still a lot of his body showing.

Some comic violence. Jack gets beaten up by a police officer. We don't see the act itself, but we later see jack with a sling and black eye. Jack staples his hand (played for laughs).

Frequent damns, hells and asses. Stronger profanities are bleeped. Some sexual euphemisms (bang, boink, etc.).

Season 3 adds s**t uncensored

Use of "bitch"

Some episodes involve smoking and drinking.

Underage drinking by high schoolers is present in the series.

Jack is shown to drown A LOT of simulation baby dolls in the school pool. This scene can be seen as frightening.
