>>1690118Actually, this reminds me of a joke:
An engineer, a physicist and a mathematician are traveling on a train through the countryside. The engineer, who has been looking through the window for a while, notices that all the goats he's seen so far are white, so he says: "looks like the goats in this region or white". The physicist corrects him: "looks like SOME of the goats in this region are white". Finally, the mathematician interjects and says: "in this region, there exist goats that are white on at least one side".
