The Stanley Parable

In The Stanley Parable, you play as Employee 427 aka Stanley, a person whos job is to push buttons. In the chapter Anomalous Materials, the first guard you interact with can say something about pushing buttons, later in the game, after going through the elevator leading to the chamber, go to the left and you will find a scientist complaining that he hates his job of pushing buttons. The scientist on the left of the entrance to the chamber has a voice extremely similar to the Narrator's voice (no not about the British accent).
