They tend to get naked more than is strictly neccesary. It was feared that having women serve on war ships would prove damaging to morale but apparently the man on man action continues to keep the men "on side".
Q. How do they separate the men from the boys in the Navy?
A. With a crowbar.
Winston Churchill described life in the Navy as "rum, sodomy and the lash". In today's modern navy, corporal punishment is not allowed in any form. Alcohol is considerably frowned upon (especially if you run your big grey war canoe onto rocks while tanked up). Sodomy however seems to be positively encouraged if not mandatory!
