Meaning of "delight the heart of a wheelbarrow"?

Question

I found this sentence in The Green Fool by Patrick Kavanagh: >I heard phrases of whimsical prophecy and exciting twists of language that would delight the heart of a wheelbarrow or a modernist poetI'm not sure what this means. Why *delighting the heart of a wheelbarrow*?

Answer 1

Heart of a wheelbarrow is basically slang, a colorful way of saying hard-hearted or humorless. It stems from the fact that a wheelbarrow is hollow and has no heart.
