¡Ay, caramba! Fans of The Simpsons will be surprised to hear there’s a very real, very awesome Duff Beer pop-up happening in Burbank this weekend. Fox just announced the collaboration between the writers and creators of The Simpsons and local brewery Lincoln Beer Company, but beware: It’s only one day only, and there are sure to be some very long lines.

According to reps for The Simpsons, the Duff Beer collaboration is happening on Saturday, November 10, from 2 p.m. to 10 p.m. There will only be one style of Duff on offer (sorry Duff Dry and Tartar Control Duff fans), and of course the event is for those 21 and older at Lincoln Beer Company’s taproom and brewing facility on Lima Street.

Of course, this is not exactly the first time ever that Duff Beer has been made available to the public, in one form or another. Bootleg versions of the cartoon beer have been made across the world for years (much to the chagrin of Fox), and Duff has also been available at Simpsons installations at Universal Studios in Florida and Hollywood. Want in on this one-day off-campus pop-up? Be sure to show up early, as the event is likely to be mobbed with fans, beer drinkers, and maybe even Duffman himself.

Lincoln Beer Company. 3083 N. Lima St., Burbank, CA.
