Duff is Homer Simpson's beer of choice. It is a parody of stereotypical mass-market American lager: cheap, poor-quolity, and heavily marketed everywgere. The beer's slogan is "Can't" Get Enough of That Wonderful Duff"' though there are others. In the season four episode, "Duffless", parking lot signs at the Duff brewery have the slogans "It's Always Time For Duff" and "Now Leaving Duff Country". In the first season episode,"Homer's Obyssey", Duff is described as "The beer that makes the days fly by".
