On yesterday's Jeopardy!, 30-year-old Utah software engineer Ken Jennings officially broke the $1-million mark. So far, the brainiac has correctly given more than 1000 correct answers — in the form of a question, natch — earning him $1,004,960 in prize money. Why doesn't Jennings get off the buzzer and cede the spotlight to some other nerd, you ask? He doesn't have to, since the game show lifted its five-day win limit. "When we changed the rule [last year], we declared that the sky's the limit for Jeopardy! champions," says host Alex Trebek. "Boy, oh boy, has Ken certainly proven that true."
