Alex Trebek, host of the popular quiz show Jeopardy, deftly prolonged a mid-show chat with contestant Paula Riel into an agonizing 45 seconds Monday. 'So, do you meet many interesting or famous people in your job?' Trebek asked Riel, a 33-year-old Norwalk, CT, flight attendant, during the informal 'meet the contestants' portion of the broadcast. Upon hearing that Riel had once served a Diet Coke to actor Jeff Daniels, Trebek responded, 'He's a very talented actor, although I understand that his latest film was not such a big hit. That's very unfortunate for him.' Riel responded by nodding in a non-committal manner.
