MADELINE: I bet his [Max’s] girlfriend’s pretty.
LOUISE: I bet she’s dumb.
LOUISE: Dumb girls crave smart men. It’s that whole Marilyn Monroe-Arthur Miller syndrome.
Hollywood actress Marilyn Monroe and left-wing playwright Arthur Miller married in 1956, after meeting in the early 1950s and dating seriously since 1955. The media saw the marriage as a mismatch, because Monroe’s typecast screen persona was a “dumb blonde”: one headline read Egghead Marries Hourglass. The couple divorced in 1961.
Lorelai and Max do fit the Monroe-Miller stereotype, as Max is written as far more literary and intellectual than the vivacious Lorelai.
