The rhyme goes like this:
One for sorrow, Two for mirth,
Three for a wedding, Four for a birth.
Five for rich, Six for poor,
Seven for a witch -- I can tell you no more.
Another version is:
One for sorrow, Two for joy
Three for a girl, Four for a boy
Five for silver, Six for gold
Seven for a secret never to be told.
A third found in Brewer's Dictionary of Phrase and Fable is:
One's sorrow, two's mirth,
Three's a wedding, four's a birth,
Five's a christening, six a dearth,
Seven's heaven, eight is hell,
And nine's the devil his old self.
