Here is mine:
"Where do the names American-style and European-style come from? I once went to a St. Patrick's Day seminar given by Nobel Prize winner Paul Samuelson at MIT (he wrote bright green socks) during which he said that he had carefully chosen the names European and American back in the 1960s. As a US immigrant from Europe, he wanted to take a swipe at snobby European economists who thought themselves more sophisticated than their American counterparts, so he named the more sophisticated exercise style American and the less sophisticated one European."
