KEN JENNINGS WILL admit that during his record-setting Jeopardy! run of 74 straight wins in 2004, he lied to Alex Trebek. It was about airline food. The host was interviewing him after the show's first commercial break, and by that point — Ken Jennings can't remember exactly when it was, at what point in the 1,800 minutes or so of airtime he occupied — but by that point, Ken Jennings had affably surrendered just about all of the harmless personal factoids he had to offer. So Ken Jennings told Alex Trebek that he liked airline food.
