Roughly 6 hours after eating at a restaurant that cooks with excessive amounts of butter, you wake up with pain and cold sweats, thus having to penguin walk to the toilet so as not soil the bed, and then cracking the porcelain. Think Harry Dunn from 'Dumb and Dumber' turbolax scene.
Holy hell, I had the butter runs in the middle of the night after eating at that hibachi restaurant. I feel sorry for the toilet.
