My brother was stopped by the police for not being a woman

Yes, it's true, my brother was driving through York and he saw the police car following him up the main road. But he didn't expect the aforementioned to pull him over. Apparently they had looked up the vehicle details and found it was registered to a woman (his partner). One might congratulate the police on this credible use of information technology but then again, one might think back to the day when O'Levels meant something!
