Okay, I am 57 and we sang a Dutch girl song that is in no way similar to anything I have read so far. I was doing a search for it, and found this page and comments. Mine is totally different. We also did hand motions to it, and I now I have the tune/melody stuck in my head. Here is the version I know:

I am a little Dutch girl
I lived across the sea
I fell in love with a rubba-dub-dub
And left the USA
He took me to his castle
And there he made me stay
First he gave me peaches, and then he gave me pears
And then he gave me 50 cents and kicked me down the stairs.

Warped, right? But I swear this is what me and my elementary friends used to sing. I have NO idea where this odd version came from.
