The tusks that clashed in mighty brawls<br/>Of mastodons, are billiard balls.<br/><br/>The sword of Charlemagne the Just<br/>Is ferric oxide, known as rust.<br/><br/>The grizzly bear, whose potent hug<br/>Was feared by all, is now a rug.<br/><br/>Great Caesar's bust is on the shelf,<br/>And I don't feel so well myself.
