A Poem on the Underground Wall - Simon & Garfunkel

The last train is nearly due

The Underground is closing soon

And in the dark, deserted station

Restless in anticipation

A man waits in the shadows

His restless eyes leap and scratch

At all that they can touch or catch

Hidden deep within his pocket

Safe within his silent socket

He holds a coloured crayon

Now, from the tunnel's stony womb

The carriage rides to meet the groom

And opens wide in welcome doors

But he hesitates, then withdraws

Deeper in the shadows

And the train is gone suddenly

On wheels clicking silently

Like a gently tapping litany

And he holds his crayon rosary

Tighter in his hand

Now, from his pocket quickly flashes

The crayon on the wall he slashes

Deep upon the advertising

A single-worded poem comprised of

Four letters

And his heart is laughin', screamin', poundin'

The poem across the tracks reboundin'

Shadowed by the exit light

His legs take their ascending flight

To seek the breast of darkness and be suckled by the night
