This Old Man, He Had One, He Played Knick Knack On My...

You may be familiar with the rhyme This Old Man, where each line goes "This Old Man, he had 1 (goes up a number with each line), he played knick knack with his ____, with a knick knack, paddy whack, give a dog a bone, this old man came rolling home.", and the word would rhyme with the number.

For example:

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

Rules:

• With each line, the number goes up by 1.
• The user must go up one number from the user above's line.
• This game will be never ending, which mean it will never go back to 1.
• If you are at a difficult number like a million and seventy 1, don't be afraid to use a word that has already been said.
• If you are struggling to think of a word that rhymes with the number, you can use slang/name/place/fictional object.

Let's start:

This old man, he had one, he played knick knack on his bum, with a knick knack, paddy whack, give a dog a bone, this old man came rolling home.
