I’m going with the race of man, it never ceases to shock me.
Back when I was a kid in New Jersey a classmate caught me reading the sports page in the library.
“What are you reading about?,” he asked.
“They just ran the 2000 Guineas (a famous horse race) in England.”
“Oh, yeah? How the hell did they get 2000 Italians to run around in a
circle?”
