The Messed-Up Muleskinner

I came across a logging camp, not exactly what I’d planned, they said they needed a muleskinner, so I told them,”I’m your man.” Up early the very next morning, I rose to go do my task, thinking they would be impressed that I’d work without being asked. At six the walking boss came out, and let loose an awful shriek, out the loggers came crying: “What did you do?! You freak!” So now I sit here in this cell, and I’m mightily confused, why did they hire a muleskinner if they didn’t want me to skin mules? I just don't understand the world anymore...
