They picked Rainn Wilson but not Ann-Margret?
Possibly just snobs rather than dummies. When Ann Margret Olsen (as she was then known) attended New Trier, the fact that she lived with her mom in the back of a funeral home tainted her with a “wrong side of the tracks” reputation. By the time I met her at Northwestern University, no one cared where she came from; her talent was too blindingly obvious. She was also one of the sweetest and most gracious of the many beautiful young women on campus.
Incidentally, one of her sorority sisters later married Rich (later “Dick” for PC reasons) Gephardt.
