Well, one's officially out of the bag, #2 is Skokie CC, in Glencoe, IL, of all places (not Skokie), and the first is the Lake course at Olympic, home club of a couple GCAers.
I figured now's the best time to do Olympic.
The first clue for Skokie was a reference to the late 70's Neo-Nazi march in the significantly Jewish Village of Skokie. Nazis rightfully claimed freedom of speech, yada yada yada. Blatant reference to it in the movie The Blues Brothers, filmed a year or two later, of course, in the Chicago area.
The Risky Business reference is much more insignificant. Given that the movie came out not long after I learned about the march in History class, the reference to Skokie stuck out in my mind. At the party, during the interview with the guy from Princeton, a friend of Joel's asks if his cousin can get "in" soon, because his cousin came all the way from Skokie. That's all. Call me Mr. Boring Trivia.
