For many viewers, a pop music round on University Challenge is a rare gem, the questions immeasurably easier than a lot of those in other topics asked by host Jeremy Paxman on the long-running BBC Two show.
But on Monday night's episode of TV's toughest quiz, the students taking part in the round found it more difficult than a toddler trying to answer a question about rocket science.
Twitter erupted with a mixture of befuddlement, glee, outrage and amusement as the contestants from Oriel College at Oxford failed to recognise three well-known classic pop hits.
Faced with intros from The Cure's Close To Me, Rudie Can't Fail by The Clash and George Michael's Faith, the four students - Monaghan, Siantonas, Helms and Thornes - just could not get one single one right.
The closest they came was that Faith was a Wham! song, and host Jeremy couldn't help but laugh at their poor attempts.
Clearly the four young men may not have even been born when the hits were released, between the years 1979 and 1987, but they're still popular enough that they might have been heard throughout their lives.
Fans of the show couldn't help themselves on Twitter, sharing a mix of pride at getting one over on the students, and also anger that they were absolutely clueless.
Maybe it's time to invest in a radio, guys.
