Shortly after being assigned to a new base, a Lieutenant and his wife were 
invited to the Colonel's home for an evening of bridge. The Lieutenant was 
partnered with the Colonel's wife and vice versa. After many hands, the
Lieutenant excused himself to use the toilet, but accidentally left the 
door ajar. When the sound of splashing echoed through the family room, his 
wife was greatly embarrassed and attempted to apologize, to which the
Colonel's wife smiled demurely, "Don't worry about it; this is the first 
time all evening that I've been able to tell what he has in his hand."
