Who is Barack Obama, NYC Mayor Giuliani, Sen. Daniel Inoyue, New Orleans' French Quarter? This evening on Jeopardy, now-seven-time winner Arthur Chu won again.

And up until the Final Jeopardy question, he almost got 'em all, but he stumbled on Britney Spears and Justin Bieber.

The Cleveland native is described on his Twitter account as a "mad genius, comedian, actor, and freelance voiceover artist broadcasting from the distant shores of Lake Erie." Tweets have noted that he's made Cleveland proud.

But on the final answer, "Only solo artist to have 5 billboard No. 1 albums before the age of 19," Chu answered, "Who is Britney Spears?" (So did another contestant, while a third suggested Shirley Temple.)

Alas, it was Justin Bieber. Pay more attention to those police blotters, Mr. Chu, even if it's not a category on Jeopardy.

But Chu still won overall, with $180,000 in his coffer, and host Alex Trebay assured fans, He'll go at it tomorrow.
