What is the oddest situation where you suddenly got an epiphany?

Mine was a few years back while I was looking for a topic for an oratorical contest. It was getting close to the deadline and I had yet to find a topic. With that concern in the back of my mind one day after I returned from school, I was cutting a piece of chocolate cake (with chocolate icing) and suddenly was struck with an idea. I found that very odd and random to be inspired while cutting cake.
