Molière
The Imaginary Invalid (Act 3 Scene 5)
SCENE V.——ARGAN, BÉRALDE.

ARG.
Brother, you'll be the cause that some misfortune will happen here.

BER.
What a misfortune not to take a clyster prescribed by Mr. Purgon! Once more, brother, is it possible that you can't be cured of this doctor disease, and that you will thus bring yourself under their remedies?

ARG.
Ah! brother. You speak like a man who is quite well, but if you were in my place, you would soon change your way of speaking. It is easy to speak against medicine when one is in perfect health.

BER.
But what disease do you suffer from?

ARG.
You will drive me to desperation. I should like you to have my disease, and then we should see if you would prate as you do. Ah! here is Mr. Purgon.
