What If It Does Fıkrası

One day, Nasreddin Hodja walks over to Akşehir Lake with copper bucket in his hands and starts pouring spoonfuls of yoghurt into the lake. Seeing Hodja near the lake with a copper bucket full of yoghurt, the curious villgaers ask:
-"What"s up, Hodja? What on earth you up to?"
-"I"m turning the lake into yoghurt" replies Hodja.
-"Reverend Hodja, could a lake ever be fermented?" the villagers retort.
-"I do know it wouldn"t, but what if it does?" is the reply from Hodja
