The Ballad of Jayne

Just finished the box set of Firefly again. This time I thoroughly enjoyed the soundtrack. A couple of days ago, half-way through the box set, I was singing the most catchy of songs, The Ballad of Jayne:

Jayne, the man they call Jayne...
The hero of Canton
The man they call Jayne

My wife in the other room asks, "Why are you singing a song about your boss Jane?"
