Marring an otherwise good article on Letterman

The New Yorker has an otherwise good blog post on David Letterman, but this mistake shows that the person who wrote the article obviously hasn't watched The Late Show with David Letterman in a while, let alone watch it on a regular basis:

But from the beginning things were a little off. Letterman made a show of running across the back of the stage before walking out to greet the audience, and then he went off to the side to talk to someone for a second or two. It’s hard to say what that was all about—nerves, blowing off steam, a pretend escape from the theatre?

The Late Show does this gag every day.
