From the aphorism «Если у тебя есть фонтан, заткни его: дай отдохнуть и фонтану» ("If you have a fountain, turn it off: give the fountain a rest, too"), by Kozma Prutkov (published in «Плоды раздумья», 1854). Kozma Prutkov, a fictitious writer, was the creation of Count Aleksei Tolstoi and the brothers Zhemchuzhnikov—Aleksei and Vladimir, with occasional contributions from a third brother, Aleksandr.
