Well, one reason is because we can’t figure out whether she was a profound intelligent woman who acted the bimbo for money, or a bimbo who could act intelligent for money. Or whether the people who thought she was intelligent were bimbos, or if the people who thought she was a bimbo were bimbos.

I once read in a bio of Marilyn that she and a girlfriend were walking down a street in NYC. They were dressed casually in slacks and overcoats. The friend was astonished that no one recognized Marilyn. Marilyn told her to wait and it was like she flipped a switch on inside of her because all at once she started being mobbed by people who recognized her. The friend said that Marilyn knew exactly what she was doing when she “flipped that switch”.
