I knew it was Frankie Lymon and the teenagers. I just wanted to lure Mark
Steyn out of his cave up there on the Androscoggin. And it worked!
(In the UK the number was covered by… who? Laurie London, I think. I bet
Mark knows… no, he’s gone back into the cave.)
In another deliberate mistake, I earlier said “open set” when of course I
meant “closed set.” Pretty much any function fails to attain its supremum
on an open set.
