Trivia: When David is cutting his hair, he is singing, "The Man Who Broke the Bank at Monte Carlo." This is a reference to the film, "Lawrence of Arabia." In Alien: Prometheus, David had a fondness for that particular movie and emulated Peter O'Toole, who played T.E. Lawrence. In the movie, Lawrence sang that song while riding on a camel in the desert.
