Chris Gamble's pick six against Ped State in 2002.
The craziest pandemonium moment I've ever witnessed while not in a stadium was Holy Buckeye. I was in the Mandalay Bay sports book. The big screen is like 40 feet across, and usually has four games playing on it, but that game was full screen. It was standing room only. There were hundreds and hundreds of people crammed in there. When the play happened, tables and chairs were overturned, drinks and food went flying, along with the ashtrays, empties, and whatever else was on the tables. There was a TREMENDOUS roar that could be heard in the venues on the opposite side of the casino floor. Some random stranger grabbed me, and hugged me, and started jumping in circles, and we fell down. It was absolute, glorious chaos.
