The 43-year-old bartender from Spanish Harlem said that, once he knew he was going to be on the show, he studied 11 hours per day for two weeks leading up to his appearance.

“It tells you that if ‘Cubist’ comes up, the answer will almost always be ‘Picasso,’” said Rogers, who only learned about this function after his run concluded.

“I watched film adaptations of well-known works that often turn up on ‘Jeopardy!’: ‘King Lear,’ ‘Sense and Sensibility,’ Bible documentaries,” said Rogers, who runs trivia nights at the Brazen Head bar in Boerum Hill.

Williams, who practiced 90 minutes a day for three months, said he used J.

“I walked around New York with a thumb exerciser on my hand; it’s normally used for rehabbing fingers and has a resistance similar to that of the ‘Jeopardy!’ buzzer,” he said
