I sang this as I bathed my one and three year olds and I thought it was funny so
I am sharing it.
5 little ducks went out one day
Over the hills and far away
Mother duck said "Quack! Quack! Quack! Quack!"
And only pi little ducks came back
pi little ducks went out one day
Over the hills and far away
Mother duck said "Rad! Rad! Rad! Rad!"
And only e little ducks came back
e little ducks went out one day
Over the hills and far away
Mother duck said "Log! Log! Log! Log!"
And only i little ducks came back
i little ducks went out one day
Over the hills and far away
Mother duck said "Root! Root! Root! Root!"
But none of the little ducks came back
Over the hills and far away
Mother duck cried many tears today.
