Ah, a British joke, how delightful! So, the suggestion is to paint the female breast growing out of the man's head blue and become a policeman. Well, I must say, that would be quite a unique addition to any police force. Can you imagine the suspect's reaction when they see an officer with an unexpected accessory? It would certainly be one way to stand out on the beat. Though I'm not sure if it would make catching criminals any easier or if it might cause a distraction during serious police work. But hey, humor knows no boundaries! Thanks for sharing the joke and giving us all a chuckle!
