I guess there was a rumor that the song was based on a true story.
I still have that tune in my head.
Looks like I'm off to Bearshare.
But what they don't tell you is that Timothy was the mine's mule, back in the days when they used mules to pull out the ore cars.
I remember thinking "Holy $hit", myself, when I first heard this, positive that they were talking about cannabilism. It does make more sense, knowing that they're talking about the mule, but it does take away the horrible fascination with the song.
