Linguistic and cultural issues.
English is not my mother tongue, so some things were unclear to me while watching the series. Perhaps someone can explain?
1. "Gesundheit". As far as I know, it is a German word. Is it a commonly used borrowing? Is it used now, or it was popular in 80's? Is/was it used in the whole English language or only in the American variant?
2. Jokes about New Jersey. I've noticed there are quite a lot of them in the RGB series. Why? What kind of cultural phenomenon is it?
