At my workplace (an airport) once upon a time, a bunch of scruffy old baggage handlers were sitting in a rec room watching porn. One old guy, who happened to hold all kinds of uni degrees, among others in ornithology, comes in. The room is all quiet, except for the sounds of the film of course. He sits there for a good while, and all of a sudden exclaims "can you hear the sparrow?" This pic reminded me of that.
