"There's your halftime show," Letterman said after Die Antwoord performed their new single "I Fink U Freeky" last night on his show. It's good that he had a quick joke lined up, because besides pronouncing their name correctly, which was a little surprising, we're not sure David Letterman could possibly have much to say about the rave-rap duo from South Africa. Check out their performance above.

Die Antwoord's album Ten$ion is out now.
