So, three friends named Mu, Bu and Fu were travelling in a boat and they were discussing. Then the following conversation started:
Mu: I'm very happy! Once we get to India successfully, I'm adding 'ck' to my name. My new name shall be 'Muck'.
Bu: I'm doing same too. I will change mine to 'Buck'.
Fu: (thinks for a while) I am changing mine to Fu.. Noo.., Peter ππ
