There used to be long toughs filled with ice in the men's restrooms at Memorial Stadium at Nebraska, back in the 80s. You'd walk up and piss on the ice. I remember going in there as a kid, and it was a game vs Oklahoma. Cold as f***. Sleetting. Wind blowing about 30 mph out of the north. This dude wearing coveralls walks in, and he is hammerd. He unzips his coveralls and starts saying, "Here dicky dicky. Here dicky," and most everyone in the restroom was laughing, including my Dad.
It's been renovated several times over since then, and now there's talk of tearing down the south end of the stadium and completely redoing it with large concourses and a restaurant/bar where you can sit/stand and watch the game from your table. Early rumors suggest anywhere from $500M - $700M reno cost, which blows my mind.
