British Literature Class, University of Pittsburgh:

Professor: [holding a novel] This edition was published in Edinburgh.
Girl #1: [to Girl #2] That’s not far from here! My ex-boyfriend goes there.
Girl #2: Yeah, I went there for a weekend last year.
Professor: [to class] As you know, Edinburgh is in the UK.
[Girls look at each other.]
Girl #1: OHHHHHHH!
[Both laugh loudly.]
