On August 27 , 2006 , at the 58th Primetime Emmy Awards , hosted by Conan O'Brien , Newhart was placed in a supposedly airtight glass prison that contained three hours of air . If the Emmys went over the time of three hours , he would die . This gag was an acknowledgment of the common frustration that award shows usually run on past their allotted time ( which is usually three hours ) . Newhart " survived " his containment to help O'Brien present the award for Outstanding Comedy Series ( which went to '' The Office '' )
