The group of rolling old men

*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 knee
With a knick-knack paddy-whack, give a dog a bone
This old man came rolling home

I think there’s something wrong with all those old men.

This old man
He played four
He played knick-knack on my sore
With a knick-knack paddy-whack, give a dog a bone
This old man came rolling home

Yeah, I think you’re right.

*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

This old man
He played six
He played knick-knack on my ticks
With a knick-knack paddy-whack, give a dog a bone
This old man came rolling home*

He seems to have a medical fetish of sorts.

And, I think I’d pay to see someone roll home.

What are the Official Rules for Tournament-Level Knick Knack?
Is it like Bocce, where you have to be an Old Man to play?

I believe that one of those old man told Churchill what to do, and now thinks he’s Saint Joan
