Physician
One prompt physician, like a sculler plies,
And all his art, and all his skill applies;
But two physicians, like a pair of oars,
Convey you soonest to the Stygian shores.
—Anonymous
Physicians, like beer, are best when they are old; and lawyers, like bread, when they are young and new.
—Thomas Fuller
