They say that America runs on Dunkin’ — but that drive-thru line might be even longer than usual today. April 1, a day unceremoniously reserved for a barrage of silly pranks and ridiculous corporate “launches,” is giving us one treat without a punchline.

In other words, Dunkin’ is offering customers a free iced coffee today in any size they desire — and no, this isn’t a well-timed prank. The coffee giant is giving away a million coffees, and the promo runs through the end of the day, which might just give you enough fuel to endure any less-than-funny jokes you encounter throughout it. The best part? You can get your free java cold, hot, or cold brew. 

“At Dunkin’ we know trust issues run high on April Fools’ Day, so we’re skipping the pranks and delivering what our guests can always count on — great coffee. This isn’t a joke, just some extra love for our Dunkin’ Rewards members,” a spokesperson told Food & Wine. 

To claim that free coffee, all you have to do is enter the promo code “ThisIsNotAJoke” in the Dunkin’ app. This limited-time offer is available only while supplies last — so we recommend starting your coffee run early. 

“Trust issues are real, especially on April 1 with most brands busy pranking their customers —but Dunkin’ is here to help,” the spokesperson added. 

They’re one to talk: Of course, the Massachusetts-based coffee chain is no stranger to an April 1 prank or two. Last year, the company introduced a “new” name change, telling customers that they were changing the chain’s name to simply “Donuts.” That announcement was just a lighthearted spin on its previous rebranding, but the chain did offer triple rewards points on doughnuts as a consolation prize.

We’ve seen our fair share of other corporate April Fools’ Day pranks turned into actual products. Consider 7-Eleven’s wackiest hot dog seltzers or Velveeta’s vivid semi-permanent hair dye collaboration with the iconic Julia Fox — both of which were actually available for purchase by the public. 

As far as April Fools’ Day surprises go, we can certainly get behind Dunkin’s take on this one
