It seems a lot of folk are keen to #MakeDonaldDrumpfAgain.

A little over a week after comedian John Oliver destroyed Donald Trump on HBO’s “Last Week Tonight,” the show announced that hats emblazoned with the catchy slogan have sold out.

“Due to, um, unexpected ludicrous demand, our #MakeDonaldDrumpfAgain hats may be delayed slightly,” said a message on HBO’s online store. ”We’ll get them to you as soon as drumpishly possible."

Oliver introduced the world to “Donald J. Drumpf” during the Feb. 28 broadcast of his show.

“Drumpf,” the comedian explained, is the Republican frontrunner’s ancestral name -- a moniker “much less magical” than the “Trump” we’re familiar with.

“Fucking Drumpf!” Oliver exclaimed. “It’s the sound produced when a morbidly obese pigeon flies into the window of a foreclosed Old Navy. Drumpf: It’s the sound of a bottle of store-brand root beer falling off the shelf in a gas station minimart.”

To promote this bit, “Last Week Tonight” filed paperwork to trademark the name “Drumpf,” and purchased the domain DonaldJDrumpf.com. A free Chrome extension that that would change all online references of “Trump” to “Drumpf” was made available online. 

“Make Donald Drumpf Again” caps, priced at $17.50, were also offered in the webstore. These hats, Oliver explained, were being sold at cost.

“We've chosen not to make a profit -- a fact which will probably irritate Mr. Drumpf more than anything else I've said tonight,” he said.

According to The New York Times, 35,000 hats have been sold to date, while the Chrome extension was downloaded more than 433,000 times.

The video of the segment has been viewed more than 20 million times on YouTube -- making it, by far, the most popular “Last Week Tonight” segment ever.
