Had a buddy challenge me to an eating contest at some chain BBQ (Bennets? Was that a thing?) place in Houston maybe 20 years ago. I've never done such a thing but I was game. The place had an all-you-can eat brisket thing going on. Your first plate was a pound of brisket, a pound of fries, two pieces of Texas toast, a half cup of baked beans and a half cup of dill pickles. After the first plate you could get more brisket a half pound at a time.
The deal was there would be no winner until one person got a full plate ahead of the other. By that rule you had to pace your competitor so speed was part of it, but you also, potentially, had to go the distance.
I won when I finished 7&1/2 pounds before he finished his 6&1/2 pound serving plate. I was more than a plate up. That came around the 45 minute mark. Bloated and miserable, and wondering why I ever agreed to this we trundled on out of the place. We were at a conference staying at a hotel and I thought walking it off was a good idea. We had about a mile, maybe a bit more to get back. About halfway back to the Hotel the rumblings started. A quick visual survey of our route indicated there was no potential relief between where I was and where I needed to get. I slowed my walk. My buddy, who had lost was enjoying my pain. Eventually it was clear I was not going to make it and I did it like a sick dog, under a bush, trying to hide from traffic. I wiped with my underwear and left my shame under that bush which I am sure either perished or grew to the size of a sequoia overnight.
Having vacated I felt better but not well. I still had considerable bloat but I was going to be fine. My buddy, who had ribbed me while I was growling in the bush suddenly got a very distressed look. The thing was, we were now well away from any likely bushes. He picked a tree for cover. The tree was maybe four inches in diameter, but was all there was. Unlike me he started spewing from both ends, instead of one. He also did not have sufficient time to situate himself to protect his clothing. Now I was laughing and cars passing by were honking their horns. He ended up laying in that grassy area while I walked back to the room to get him some unsoiled clothes so that he could return to the Hotel.
Answer, to the OP question, anything except bad brisket at a cheap chain BBQ place.
Oh... The hotel lost two towels that night as I took my buddy a wet and a dry towel along with the fresh clothes.
