The Man Who Talked to the Walls

"Once, when I was runnin' to the shop,
I noticed a sight both amusing and strange
A man talking to the walls as if they were alive,
Compelling me to infer that he was insane"

"Again, when I was retreating from an oncoming car
I saw the same man talkin' to those walls
But this time I completely lost control
I exploded with laughter, collapsing on the sidewalk"

"Not at all distracted, he kept conversing with 'em
And without warning, took out a gun
Shot the poor things like they were alive and well
Once the standoff concluded, he sat munchin' a bun"

"Although my instincts pressurised me to do so,
I didn't call the police to arrest the guy
He was so shaken, I simply left
Until a wall shouted, "Goodbye, my boy!!"
