What's the sound of a thousand rabbits shitting in your ear?
Purkin was a nature freak. He could track sparrows by the thickness of the shit on the branches. Everywhere he traveled he would collect turds. He had what was perhaps one of the finest scat collections in the galaxy. That all got ruined when his son wanted a dog. The little guy had to have a dog or he was gonna run away. That dog ate his entire collection the first night he was there. A decade's worth of work recycled.
Purkin's son became quite the tracker himself. Though he never did get a handle on the scat reading. Purkin remains to this day probably the fastest crap dicer I have ever seen.
