Sometimes there are “Jeopardy!” answers that no one can forget.

That was the case on Monday, when one contestant mixed up two British icons.

In the “Knight After Knight” category, a photo of Michael Caine appeared on screen.

The answer: “This star here was knighted in his birth name, Sir Maurice Micklewhite.

The correct answer: “Who is Michael Caine?”

Unfortunately, contestant Mazin Omer replied, “Who is Mick Jagger?”

Many fans watching along at home took to Twitter to comment.

“The Michael Cain/Mick Jagger response will live on as an historic bad answer,” one tweeted.

“I am FLABBERGASTED at this guy on jeopardy who thought michael caine was mick jagger,” another user wrote.
