This old man
He plays two
He plays knick-knack on my shoe
With a knick-knack paddy-whack
Give a dog a bone
This old man comes running home

This old man (this old man)
He plays three (three)
He plays knick-knack on my knee (my knee)
With a knick-knack paddy-whack
Give a dog a bone
This old man (this old)
Man comes running home
This old man comes running home
