Stale Cheese: Last Comic Standing

Two comics went head to head last night at the end of NBC's Last Comic Standing. The way the competition was presented led us to believe that the two comics were about equal: they got the same number of laughs. However, after the audience's vote was counted, we were told that 94% of the people who were actually there voted for the same comic. Now, why was the show edited to make us wonder who would be tossed off even though it would have been extremely obvious had we been allowed to see the whole performance?
