Our doctors

“So, colleague, what have you come up with regarding cholera?”
“In case it appears in our city, I won’t take less than 25 rubles for a visit.”
“Bene; and that’s how I’ll travel around the cities.”
“What for, won’t there be enough patients for both of us.”
“It’s not that. As soon as cholera appears in the city, I’ll skip town and keep studying this disease in uninfected locales.”
(Razvlechenie, Moscow, 1883)
