Zippy the Pinhead is a fictional character who is the protagonist of Zippy, an American comic strip created by Bill Griffith. Zippy's most famous quotation, "Are we having fun yet?", appears in Bartlett's Familiar Quotations and became a catchphrase. He almost always wears a yellow muumuu/clown suit with large red polka dots, and puffy, white clown shoes. Although in name and appearance, Zippy is a microcephalic, he is distinctive not so much for his skull shape, or for any identifiable form of brain damage, but for his enthusiasm for philosophical non sequiturs, verbal free association, and pursuit of popular culture ephemera. His wholehearted devotion to random artifacts satirizes the excesses of consumerism.

A comic strip is a sequence of cartoons, arranged in interrelated panels to display brief humor or form a narrative, often serialized, with text in balloons and captions. Traditionally, throughout the 20th and into the 21st century, these have been published in newspapers and magazines, with daily horizontal strips printed in black-and-white in newspapers, while Sunday papers offered longer sequences in special color comics sections. With the advent of the internet, online comic strips began to appear as webcomics.
