Ken Jennings, who rose to mid-level fame by winning a record $2.5 million on Jeopardy last year, was erroneously identified as Subway restaurant pitchman Jared Fogle again Monday. 'Today a woman at the post office came up and congratulated me for losing all that weight,' Jennings said. 'That happens all the time. I guess people recognize me from television, but mix up where they saw me.' Jennings added that he usually tries to inform people of their mistake in the form of a question: 'What is your problem?'
