A Xbox commercial that came out just before Gears of War 2 was released featured John, wearing a Marcus-style doo-rag, going into Marcus' voice and barking: "Dom! Cole! Baird! Get over there and do...something!"
In the same period, a video was released in which he talks about playing with himself in the game. This leads into John talking about how he likes to "come home, take his pants off and play videogames!".
