The problem is when you take something out of its time and see every portrayed character as stereotype - you will kill all humor in the end. Imaginge some todays series in 10 years. There will always be some further developed people who adapted their own human being to whats morally acceptable in given time.

Ask people who are “affected” by the humor and if they are offended. Or make jokes about growing grass.

This only happens if you slip into Season 9 in my mind.

Sounds like straight out of Family Guy… Hehehehe.
