My brother came back from school all motivated because he said he would be following a new diet from that day. We didn't really give it much thought until my brother really started eating his homework for dinner. When we stopped him and asked why he was doing that, he replied, "I was just trying to see how it tasted because my teacher said that the homework would be a piece of cake for me."
