Raphael (also commonly known as the Sarcastic Clerk, Wiseguy, or Middle-Aged Man) is a recurring background character in The Simpsons - his main purpose is to carry out a job or sell a product that gets a plot rolling. His voice is also often used for loudspeaker announcements. Raphael's character model has varied perhaps the most of any recurring character, with hair color, style and mustache all changing despite his distinctive voice. It wasn't until later seasons when the page image became the standard model for when his voice is used. Raphael tends to make dry comments when confronted about the prices or quality of his services. He has even been sarcastic towards Comic Book Guy. (Source: Fandom.com, CC BY-SA)
