OK, so this is partially to help me with my revision, and also just because I think it's a small amount of fun.. I usually like doing these, but now I am totally stuck on them for some reason today... Format goes like this: * = They have to be true in a sense, as long as they fall into what people perceive to be true, then all's well. For example, one could have "All Unicorns are magical horses." The best I've got so far: All dogs are animals Some animals are cats Therefore, some cats are animals. You get the idea... Can anyone think of any?
