The surprising discovery that the rather seeming ordinary pulsar B1931+24 can be OFF for weeks at a time has created a potentially important advance in theoretical understanding of how pulsars work. A number of other pulsars with similar behaviour are known. On the one hand we may understand why pulsars do not have a deceleration index of 3. On another we can see an outline of why pulsars remain inclined. More importantly we have an opportunity for understanding the relationship of the well known Goldreich-Julian model with the widely misunderstood Kraus-Polstorff-Michel (1985).
