Yeah. A house.
It was in the road.
It wasn't there when I passed the same spot this morning, leading me to three likely conclusions:
1) Someone built a house in the road, and did it in record time.
2) It came from somewhere else, and wandered into the road on its own.
3) Someone was towing a house, and either accidentally dropped the trailer or was grossly mistaken about where it was to be delivered.
If we assign an equal probability to each, we end up with a 66.6% chance of total bizarreness.
I'm okay with living in a world that's 2/3 bizarre. I considered parking nearby and running around in front of the house screaming at the passing cars to 'get the hell out of my yard!'.
