Turn: The True Story of losing dead people

This story happened in the first-class U.S. university in October 1 last year. In the biology class, the professor is explaining that the semen contains a high proportion of glucose. A girl raised her hand and asked, "If I understand it correctly, what do you mean?
「 Yes !」 The professor replied and prepared to add some data. The girl raised her hand and asked, "Why isn't it sweet ?」?
After a silence, the class burst into laughter, and the poor girl finally understood what she had accidentally said (or hinted at), blushing, picked up the textbook, and did not say a word, walked out of the classroom.
However, when she stepped out of the door, the professor's response was really classic!
