Wednesdays child is full of woe

I can't get the childrens rhyme out of my head today. You know this one? It goes -

Mondays child poem

Mondays child is fair of face,
Tuesdays child is full of grace,
Wednesdays child is full of woe,
Thursdays child has far to go,
Fridays child is loving and giving,
Saturdays child works hard for his living,
And the child that is born on the Sabbath day
Is bonny and blithe, and good and gay.

I'm a Wednesday child, and the first time I heard this as a kid I remember wondering why being born on Wednesday had to be so bad. Everyone else on that list has good things going on for them - good looking, graceful, a traveler (now that's what I'd be picking!), loving, giving, hard working, "bonny and blithe and good and gay" - hey, Sunday rocks! Want to bet a Christian wrote this dity?

But why do we Wednesday kids have to get such a bad rap?
