a) That oiled-up guy from Tonga who walked in the opening ceremony at the Rio 2016 Summer Games, Pita Taufatofua, suddenly appearing in the same outfit at the top of the PyeongChang 2018 Winter Games halfpipe to announce, as he locks himself into snowboard boots, that he will now throw down — watch out, Shaun White — an unprecedented trick involving corks, flips and other head-spinning gyrations;

b) George McGovern running for president of the United States in 1972;

c) Any city in Europe winning a ballot referendum on the notion of staging the Summer or Winter Olympics;

d) All of the above.
