Molière
The Imaginary Invalid (Act 3 Scene 8)
SCENE VIII.——ARGAN, TOINETTE, BÉRALDE.

TOI.
(to Argan). There is a doctor, here, Sir, who desires to see you.

ARG.
What doctor?

TOI.
A doctor of medicine.

ARG.
I ask you who he is?

TOI.
I don't know who he is, but he is as much like me as two peas, and if I was not sure that my mother was an honest woman, I should say that this is a little brother she has given me since my father's death.
