Harry and Fred both bought one horse each. They wanted to make sure that they feed their own horse each morning. So Harry asked, “how will we know which is your and which is mine?” Fred said “its easy I will cut mine’s tail and yours will be the one with tail”. Some boys outside heard it and cut the tail of other horse too. So the next morning confusion arose even more. Harry said, “don’t worry, I”ll tie a bell around its neck, yours will be the one without the bell”. The boys heard this too so they cut the bell. The next day, Harry got frustrated and said, “OKAY!!! now the last criteria will be that: White Horse will be yours and Black Horse will be mine”.
