Aflac

An American Life Insurance company that has a line of commercials featuring a duck that mysteriously acquires the abnormally-loud voice of Gilbert Godfried. The unnamed duck can only say the name of the Life Insurance company he, for some unexplained reason, endorses: "Aflac." The duck has the ability to appear anywhere in the world where a Life Insurance-related conversation is taking place. However, no human can actually hear his "advice."
