Here is how the song goes:

This old man, he played one
He played knick knack on my thumb
With a knick knack paddy wack
Give a dog a bone
This old man came rolling home.

This old man, he played two
He played knick knack on my shoe
With a knick knack paddy wack
Give a dog a bone
This old man came rolling home.

This old man, he played three
He played knick knack on my knee
With a knick knack paddy wack
Give a dog a bone
This old man came rolling home.

This old man, he played four
He played knick knack on my door
With a knick knack paddy wack
Give a dog a bone
This old man came rolling home.

This old man, he played five
he played knick knack on that hive
With a knick knack paddy wack
Give a dog a bone
This old man came rolling home.

This old man, he played six
He played knick knack on my sticks
With a knick knack paddy wack
Give a dog a bone
This old man came rolling home.

This old man, he played seven
He played knick knack up in heaven
With a knick knack paddy wack
Give a dog a bone
This old man came rolling home.

This old man, he played eight
He played knick knack on my gate
With a knick knack paddy wack
Give a dog a bone
This old man came rolling home.

This old man, he played nine
He played knick knack on my vine
With a knick knack paddy wack
Give a dog a bone
This old man came rolling home.

This old man, he played ten
He played knick knack once again
With a knick knack paddy wack
Give a dog a bone
This old man came rolling home.
