A traditional nursery rhyme with finger play. You can hear a more musical version here: This old man.

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

This old man, he played five,
He played knick-knack on my hive.
With a knick-knack, paddy whack,
Give a dog a bone,
This old man came rolling home.
