This article describes a practical example of the predicate grue, examining the economic relationship between the percentage rate of unemployment and the percentage change of money wage rates known as the simple Phillips curve which exhibited regular behaviour before 1969 and erratic behaviour thereafter. It is proposed that such practical examples of grue from the real world be redescribed as regulatic. i.e. regular before time t and erratic thereafter. In the instance of a scientific model or theory being falsified it is proposed to describe the predicate astralse, i.e true before time t and false thereafter. The example to be discussed is a stronger example since entities in the real world started to behave in an extremely unpredictable fashion.
