I saw this in a magazine (American Girl, I think) when I was a young teen:

Come live with me and be my love
And have such pleasures far above
Those which other woms can give,
If you will come with me to love.

Oh, no, this thing can never be
Though you may seem so much like me.
We cannot wedded be, my friend,
For I am but your other end.

To which my mother (I think) quipped,
"Or, maybe it should be
"For I am butt, your other end!"
