There's been a lot of favorite songs mentioned here but I don't think anyone has mentioned the one that my mother still sings at the age of 91:

...You makes love dandy;
You're as sweet as molasses candy,
But tell me, honey, are you makin' any money,
That's what I'd like to know!

This is probably a country-western song from the 1940's but I can't find it.

Cheerily,
Charley Noble
