I was really excited to see how a 19th-century landscape painter was connected with one of the best NBA players of the 1980s and an Ancient Greek mathematician. Not what I got, but the actual subject is still pretty interesting.
I remember taking a PL class in undergrad, learning Prolog as one of a handful of languages. During that section my brain started to want to "bind" variables to things as I was going about my day, it was very weird.
