The Antelope and Cantelope
Lie side by side upon the slope,
And careless persons might, I fear,
Mistake the melon for the deer.
If you will tap the Cantelope, reposing on the ground,
It does not move, but just emits a melon-choly sound;
But should you try, however, to apply a stethoscope,
And attempt this auscultation on the antlered Antelope,
And should see an imitation of a very rapid flight,
And should say, “It is the Antelope!” I think you would be right.

From Animal Analogues (1908), by Robert W. Wood, author of How to Tell the Birds From the Flowers.
