At BRNC Dartmouth just a few weeks after the first WRNS Officers had arrived (1977) the Royal Marine Colour Sergeant (Don't call me Colours I aint a **cking rainbow) was drilling some young male officers. The young WRNS officers were waiting for their turn and were all giggling at the tick tocking etc of the blokes. The CSGT halted the platoon of men, marched smartly over to the WRNS and said 'I don't know what you lot are laughing at you've only got one c*nt to look after, but I've got 24'. Fortunately PCness had not arrived in the RN then, so they just went quiet and looked sheepish!
