Now I lay me down to sleep,
The king-size bed is soft and deep.

I sleep right in the center groove 
My human being can hardly move! 
I’ve trapped her legs, 
she’s tucked in tight, And here is where I pass the night. 
No one disturbs or dares intrude
Till morning comes and I want food! 
I sneak up slowly and it begins
My nibbles on my human’s chin.She wakes up slowly groans and shouts, “You rotten beast! Just cut it out!” 
But morning’s here and it’s time to play 
I always seem to get my way. 

So thank you, Lord, for giving me 
This human person that I see The one who hugs and holds me tightand shares her bed with me at night!

The original is a night time prayer taught to many children.

Now I lay me down to sleep,
I pray the Lord my soul to keep,
If I should die before I wake,
I pray the Lord my soul to take. Amen.

(Cheerful stuff.)
