His passage at a narrow door,
And scarce could reach the rack of hay,
His horns so much were in his way.
A Calf officious, fain would show
How he might twist himself and go.
"Hold thou thy prate; all this," says he,
Ere thou wert calved was known to me."
He, that a wiser man by half
Would teach, may think himself this Calf.
