Overheard at the Village Inn, 3 AM.

A group of young people was seated next to me just now.

Girl, thumbing her smartphone:  "Do you know that a PhD is a 'Doctor of Philosophy'?"

Boy sitting next to her:  "No!  You mean that's what it means?  No.  What does it mean?"

Girl:  "'Doctor of Philosophy.'  PhD means 'Doctor of Philosophy.'  That's what it means!"

Boy:  "No!  Really?  No!"
