I was reading the link that Lisa posted, and at the bottom of it there was this rhyme

"Sneeze on Monday for health,
Sneeze on Tuesday for wealth,
Sneeze on Wednesday for a letter,
Sneeze on Thursday for something better,
Sneeze on Friday for sorrow,
Sneeze on Saturday, see your sweetheart tomorrow,
Sneeze on Sunday, safety seek.

One for sorrow
Two for joy
Three for a letter
Four for a boy.
Five for silver
Six for gold
Seven for a secret, never to be told. "

okay, so the bottom part is part of a counting crows song...the only difference is "three for girls" instead of "three for a letter"....
I can't remember which song, but it's on August and Everything After....
