The Two Doctors by Unknown Author

Said Dr. Do, "Drink lots of milk;
Eat toast—there's nothing better;
And soon you'll feel as fine as silk,
And sprightly as a setter."

Said Dr. Don't, "Avoid all meat,
And deadly fried potatoes;
No coffee, mind; and never eat
Bananas or tomatoes."

And Dr. Don't became a grocer,
His patients were so few,
The sick folks all said: "Don't? Oh, no, sir!
I go to Dr. Do."
