made a big boo-boo during Monday night’s game when he incorrectly guessed the answer to a question involving Sir Michael Caine.Contestant Mazin Omer picked a question for $400 and was given a photo of Caine, 89, holding up his knighthood badge.“To honor his father, this star here was knighted with his birth name, Sir Maurice Micklewhite,” host Mayim Bialik said.Omer wrongly replied back, “Who is… Mick Jagger?”After his mistake, contestant Lisa Hernson quickly buzzed in and correctly said that the clue was regarding Caine.The “Batman Begins” star was knighted in 2000 by Queen Elizabeth for his services to British film and drama.
