Frederick Hobart Mertz, played by William Frawley, is a fictional character in the 1950s American sitcom I Love Lucy. When Ricky does something to upset Lucy, she plots revenge and drags Ethel into her plan, often against her will. Ethel almost always blabs to Fred, who tells Ricky, and the two come up with their own plan to get even with their wives. Once in a while, it is Ethel who is away and it is Fred who is dragged into Lucy's scheme. Usually, Fred expresses his exasperation with a phrase: "Oh, for corn sake". The Fred Mertz character, the actor who portrayed him (William Frawley), and some of their costumes are memorialized in the Lucille Ball-Desi Arnaz Center in Jamestown, New York (Lucille Ball's real-life hometown). Due to the personality of the television character, the name "Mertz" is sometimes used as a description of someone acting in an unaware or unconscious manner. For example, someone walking with his zipper down or food on his face may be described as being a "Mertz"
