It has been one of those weeks for broadcasting legends everywhere, it seems.
David Letterman, who has featured on his show no fewer than four US presidents and about every half-decent American comedian of the past three decades, said a final goodnight after 33 years in late-night comedy.
He was his wisecracking self to the end. There's a lot to be said for going with dignity.
But all gushy nostalgia aside, an audience with Letterman recently could be a bit hit-or-miss. You could turn up one afternoon to watch the show with every tourist in Times Square and be treated to an hour with the biggest pop names and movie stars in the world.
But you could also turn up, as we did, on a random Tuesday, for a tepid monologue and three interviewees we'd never heard of.
