CAT. Can you purr?
DUCKLING (frightened). No.
HEN. Then you can't stay here.
DUCKLING. Do not drive me out, I pray you!
CAT. Will you learn to purr?
HEN. And to lay eggs?
DUCKLING (sadly). Alas, I can do nothing but swim.
CAT. Swim! Well, I must say that is very queer.
DUCKLING. Oh, no, dear sir! It is most pleasant when the waters close over your head and you plunge to the bottom.
CAT. Plunge to the bottom, indeed! I'd never think of doing such a silly thing!
