Best Sexual Euphamism Ever

From the interview in the New York Times Magazine. What makes it so good is that it's clearly dirty, but still a little cryptic:

I read somewhere that you and Hillary dated when she was still at Wellesley.
To call it a date is an exaggeration. She and I went out to see Antonioni’s “Blow-Up.” The only thing I remember is that she wanted what seemed to me to be an extraordinary amount of butter on her popcorn.

[UPDATE: Forgot to mention, for those who didn't click the link, a good deal of the hilarity is that the interviewee is Robert Reich.]
