Ten In A Bed

(From "Calusari" Episode | Used During: Opening teaser. The mom sings this to her son before he gets hit by the train.)

There were ten in a bed
And the little one said
"Roll over, roll over"
So they all rolled over
And one fell out

There were nine in a bed
And the little one said
"Roll over, roll over"
So they all rolled over
And one fell out

There were eight in a bed
And the little one said
"Roll over, roll over"
So they all rolled over
And one fell out

There were seven in a bed
And the little one said
"Roll over, roll over"
So they all rolled over
And one fell out

There were six in a bed
And the little one said
"Roll over, roll over"
So they all rolled over
And one fell out

There were five in a bed
And the little one said
"Roll over, roll over"
So they all rolled over
And one fell out

There were four in a bed
And the little one said
"Roll over, roll over"
So they all rolled over
And one fell out

There were three in a bed
And the little one said
"Roll over, roll over"
So they all rolled over
And one fell out

There were two in a bed
And the little one said
"Roll over, roll over"
So they all rolled over
And one fell out

There was one in a bed
And the little one said
"Good night!"
