Quotations
Well, a certain zaftig coed told this on herself. She tried to give her all to Brainy in exchange for a passing grade in the general math course necessary to any degree on our campus. […] "Brainy" didn't accept, didn't refuse, wasn't offended, didn't seem to understand. He told her that she had better talk to her instructor about getting tutoring and a re-exam. Now Miss Zaftig is circulating the story that Prof "No Brain" must be a eunuch or a robot. Not even a homo. Totally sexless.
1980, Robert A. Heinlein, chapter VII, in The Number of the Beast, part one, pages 61–62
