That day, for no particular reason, I decided to go for a little run. So I ran to the end of the road, and when I got there, I thought maybe I'd run to the end of town. And when I got there, I thought maybe I'd just run across Greenbow County. Now, I figured since I'd run this far, maybe I'd just run across the great state of Alabama. And that's what I did. I ran clear across Alabama. No particular reason. I just kept on going. I ran clear to the ocean. And when I got there, I figured since I'd gone this far, might as well turn around, just keep on going. And when I got to another ocean, I figured since I'd gone this far... I might as well just turn back and keep right on going. When I got tired, I slept. When I got hungry, I ate. When I had to go... you know... I went.
