My pet is a mammal and it doesn't have sonar. So it doesn't fly. Some fish care for their young. No fish that care for their young are nothobranches. So some nothobranches are not fish.
All beautiful actresses are famous.
Jane is beautiful, but she is not an actress. So Jane is not famous. Some people like okra and some don't. People who like okra are strange. All poor people eat at McDonald's.
