What the h-e-double hockey sticks

Last night coming home from a softball game, I passed gas stations (no the "S" is not a mistake) that had gas for $3.35 a gallon. Several stations...so my mood was improving. This morning the gas station across the street said $3.65 and so does every station I have seen today. What happened in the five hours that I slept that made gas go up thirty cents a gallon? Now I'm pretty tired, but I really don't want to take a nap.
