Knick-knacks are those little porcelain figurines. A paddy can either be a rice field or an Irish person (the hit man's last name is McClain). And to whack something means to kill it.
Knick-knack paddy whack is a nursery rhyme.
(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.) It's a play on words with a nonsense nursery rhyme :)
