Scotty's Prayer

I bought Scotty the book of Mother Goose Rhymes a couple months ago and lately I think he's been getting a particular rhyme confused with his prayers. Here's how his prayer goes:

"Dear Heavenly Father,
Thankyou you for Grandpa, Grandma, Sister and a Wife,
Who cut off their tails with a carving knife.
Thankyou for the food.
In the name of Jesus Christ,
Amen."

Now here's the nursery rhyme he's alluding to:

"The Three Blind Mice"
Three blind mice, three blind mice;
See how they run, see how they run!
They all ran after the farmer's wife,
Who cut off their tails with a carving knife.
Have you ever seen such a sight
In your life as three blind mice!

How he got that part in there is a mystery to me! =)
