Here's one I heard Robin Williamson sing. I'm sure I would have picked it up as a kid if I'd heard it then, because it sounded so jaunty and innocent.:

Me wife's got a furry thing,
A furry thing, a furry thing.
Me wife's got a furry thing;
She showed it to me Sunday.
It came from the furrier's,
It came from the furrier's,
It came from the furrier's;
It's goin' back on Monday!
