There was a time I was in the University and did not know how to cook. So I had this fellows who do the cooking whilst I do the dish washing. So one day they decided to prepare yam, so they asked me to peel the yam. This is where the funny part is. The first peeling did not just remove a peel, it rather peeled the yam and the rubber bowl in which I was peeling the yam. All they could do is laugh.
