Common Sense Note
Parents need to know that this often-silly sitcom follows a bunch of remedial students attending an inner-city high school. Teens make fun of each other constantly, calling guys things like "cream puffs" and women "dogs," but other than that, the language is pretty clean. Race, poverty, and drug/alcohol use are occasional topics, though the treatment of the issues is always sanitized. The students are under-achievers, and their apparent stupidity is a source of humor.
Mr. Kotter and his wife sometimes kiss and hug chastely. Discussion of dating and making out. Some episodes feature sexy Sweathogs with some sexual innuendo.
Off-screen fighting, some physical threats -- all slapstick humor.
Insults fly regularly, like "cream puff" for a weak male, and "dog" for an ugly female.
Students engage in some troublesome behavior -- minor stealing, truancy, etc. -- but these incidents mostly lead to moral lessons. Kotter helps the students that others treat poorly, showing that you don't have to be smart or rich to deserve respect. That said, the students' chronic underachievement and lack of smarts are often tapped for laughs.
Drugs / Tobacco /
Rare episodes deal with drug and alcohol addiction, though without graphic detail.
