This old man, he played one, He played knick-knack on my thumb. (on a drum, on my tongue) With a knick-knack, paddy whack, Give a dog a bone, This old man came rolling home.
"The term "Paddywack" was used from at least the early nineteenth century to describe an angry person, specifically a "Brawny Irishman". From at least the 1970s sensitivity over possible racism has meant that the song is often sung as "Knick-knack patty-whack", particularly in the United States."
And, you have been warned, - do not Google "Give a dog a bone".
