This poem comes from Autumn Leaves:

Mumbo, Jumbo! Mumbo, Jumbo!

Monotone; loud and clear,

Bouncing off hallowed walls,

Bouncing off my ear.

Ears hear the words, but then,

They don’t really listen.

There are words and words, piled on top of words,

Yet the message is somehow missing.

To class you go, anticipation aglow,

Completely, academically gird.

Oh, Boy! What joy! You hear words,

And words, on top of words.
