On Monday, British prime minister David Cameron announced that he would step down from his post on Wednesday, whereupon he will be succeeded by home secretary Theresa May. Walking back to 10 Downing Street after his announcement, Cameron forgot himself—and his live microphone—for a moment, humming a little ditty.

Crossing the threshold, Cameron states, plainly, “Right.” There is a rustling noise as the microphone is disentangled from his suit jacket. “Good,” Cameron adds.

Carry on then, David. Stiff upper lip and all that.
