Fastest a Super Bowl Has Ever Felt "Over"?

I'm too young to remember the blowouts of the 80s and 90s but I thought it was funny how even when the Eagles were up 24, even 27 points people didn't think it was over. It wasn't until the deep TD that made it 34-0 that all my friends went "okay now this is over." What was the earliest a Super Bowl ever felt over? I, kind of jokingly, think of the ball getting snapped over Peyton's head on the first play of Super Bowl XLVIII but that game was only 8-0 at the end of the 1st and didn't get ti 3 scores until Malcom Smith's pick six with 3 minutes left in the half so maybe people watching thought the Broncos had a chance I can't really remember
