I remember when I'd go to the games way early back in the day to get seats right on the 50 because the student section was first come, first serve. The stadium would be nearly empty except for some of us in the student section. The is back when The Wave was a thing. So there'd be one guy sitting alone on the other side of the field at, say, the 40 and we'd start a wave in the student section and then point to where The Wave would be if the rest of the stadium was full.
So we'd do our wave at the 50, 45, 40, beyond which there was no people left to wave, so we'd point to the 35, 30, 25, 15, 10, 5, goal line, endzone, across the endzone where the facilities building was, to the goal line on the other side, then 5 on the other side, 10, 15, 20 25, 30, 35, and then the guy sitting on the 40 would stand up and put his arms up and yell and sit back down like he was doing The Wave with us. It was pretty damn funny to see although it probably doesn't come across in words.
