Did you get the broom closet ending?

In The Stanley Parable, you can walk into a broom closet, and the narrator mocks you for doing so and wonders if you think that doing this will make anything happen or unlock any more content (the irony being, of course, that the extra narration is the extra content). Then the narrator does an impression of someone talking about the game, and says "Did you get the broom closet ending? The broom closet ending was my favorite!"
