Al Franken stumped Sonia Sotomayor on a question about 'Perry Mason.'"]WASHINGTON (CNN) - The White House may have quizzed Judge Sonia Sotomayor on endless laws and past court cases, but Sen. Al Franken thinks they might have missed something.
"What was the one case in Perry Mason that Burger won?" Franken asked Sotomayor at the end of his questioning session on Wednesday afternoon.
Franken and Sotomayor discovered earlier that they were both avid fans of the television show, Perry Mason, which featured a defense attorney who specialized in extremely difficult cases. Sotomayor said she couldn't remember the name of this particular episode, in which Mason loses to prosecutor Hamilton Burger, but said she was "struck" that it was the only one in which Mason's client was actually guilty.
"Didn't the White House prepare you for that?" Franken said, to laughs.
But Sotomayor had a good excuse.
"You are right, but I was spending a lot of time on reviewing cases," Sotomayor said. "I do have that stark memory, because, like you, I watched it all of the time, every week as well. I just couldn't interest my brother, the nurse, and my brother, the doctor, to do it with me."
Turns out, Franken didn't know the answer either. Sen. Patrick Leahy, the Judiciary Committee Chairman, asked the Minnesota lawmaker to tell everyone the name of the episode.
"I don't know," Franken said. "That's why I was asking. If I knew, I wouldn't have asked her."
Since Franken didn't know the answer either, Leahy said Sotomayor was off the hook.
"Because of that, judge, we will not hold your inability to answer the question against you," Leahy said.
Mason lost to Burger just a handful of times on the show, which originally ran from 1957-66.
