I wasn't near the TV but there was an Allstate commercial, and the Final J! music was playing in the background, and I wasn't paying attention, but I swear Ken Jennings is in this commercial. Dennis Haysbert does his spiel, and the guy in question ponders his answer for a moment, and finally gives his answer, which is "correct." Anyone who's seen the commercial, feel free to confirm or deny.
If this is "Woolery Left Wheel" news, kiss [off]. :-P
