Usually no violence, except for occasional slapstick stuff. In one episode, a man is killed during a hate crime outside the Bunker house. Discussion of other crimes, including rape.
Some very tame allusions to Mike and Gloria's sex life. Some brief kissing. Discussion of sexually related issues, like homosexuality.
Some mild cursing, like "hell" and "dammit." Occasional bigoted language, like the n-word and derogatory terms for homosexuals.
