Big weasel don't you whine

So I was playing Jim Croce's Big Wheel this afternoon on a little break after a meeting.  I'm working from home today and get to do that.  It's nice.  Anyway, the first two lines are Big wheel don't you roll, big diesel don't you whine..."

I didn't have my head clear and on the song, and there's a Bm to kick off the third stanza and that's never a good thing.  So how did I sing it, "Big wheel don't you roll, big weasel don't you whine..."  So then I've got an image of an overgrown ferret all wrapped up around a play ball rolling along the floor and there's no chance I'm going to hit the Bm at that point. 

I just liked that image of the big weasel rolling down the road on the way to Baltimore, avoiding radar traps and turning down coffee.
