If you think this little piece of doggerel is risque, then you must have a very dirty mind. I don't know where you get ideas like that from! I think I made this up because I wanted to read something over the phone to my mother that would make her laugh. If I remember correctly, I got to the end of it and she said, "That's it?"
I love you-know-who, you know how much,
’Cause she’s just such a such-and-such;
And ev’ry time she—well, you know—
My you-know-what does thus-and-so.
