A Decade's A Decade

I was watching The Ice Storm (1997), a pretty decent film set in the '70s--1973, to be exact. It really captures the look of the period.

But I was taken out of it when Tobey Maguire referred to Christina Ricci's parents as "parental units." Yeah, I know, the phrase comes from the 70s, but in particular, it comes from the Coneheads' sketches on Saturday Night Live, the first of which aired in 1977.
