He makes oblivion serve his need,

When he would act the noble steed;

He kicks, he plunges, and no sneers

Can point him to his monstrous ears;

The swift he banters to the race,

And, for a time, keeps up his pace;

But wind and metal soon give out;

“Why, Jack, what brings this change about?”

Quoth Jack, “My boasted sire, alas,

Was after all an humble ass!”
