This blog is heretofore devoted to subtle memes. Let's set us off:
1) People who talk about Kermit Roosevelt - from a historical perspective - with a perfectly straight face, as if it's not hilarious that his name is Kermit Roosevelt i.e. "Kermit Roosevelt was a principal architect of detente! Kermit Roosevelt was a raging alcoholic!" etc...
2) Telling a story where you implicitly demonstrate your knowledge that Al Gore and Gore Vidal are related, but no "Did you know they are related?" as if to say "Of course I know that they are related, as does everyone who I communicate with. If it were news to me or any of my audience, I would be working at The New Republic, not the New Yorker..."
e.g. "Gore Vidal gave a prescient speech at Al and Tipper's wedding on the future of globalization..." e.g. "Obvi Gore was at their wedding! they are related..."
