What is that which has been to-morrow, and will be yesterday?
To-day.
My habitation's in a wood,
And I'm at any one's command;
I often do more hurt than good,
If I once get the upper hand:
I never fear the champion's frown,
Stout things I oftentimes have done;
Brave soldiers I have oft laid down,
I never fear their sword and gun.
A Barrel of Beer.
