Thanks, Ken. Might have known you'd have these.

Is there anybody who can elucidate a couple of the technical points:

"Her grub is low and her pump rods shine" - what's a pump rod, and why is it, apparently, a bad thing for a pump rod to be shiny?


"Her nose is blunt and she keeps a crank" - the blunt nose part is easy, but what's "keeping a crank"?

Not that I have to have the technical info to sing the songs, but I'm curious.
