I always disliked that term because upon reading the Holy Book it'd conjure up bad feelings that I would have suppressed. But anyhoo, here's a Game Theory like conundrum:
Suppose you enter Heaven. Then you are met by five Arabian-Romanesque caryatid like houris. Only one of them is telling the truth is pretty and has good character and choosing the right answer will open the pearly gates.
H#1= Choose me I am pretty and because all of them are damn liars except me!
H#2= Choose me because 3 is lying. I am an intelligent enough to grasp that.
H#3= Choose me because I am pretty and I always tell the truth like 1 is telling the lies.
H#4= Choose me because to be honest #2 is blind to the fact that she is ugly. And I don't lie...
H#5= I am ugly please don't choose me to tell you the truth because every time I lie only truth comes out!
Which houri do you choose who has all three qualities: beauty, character:honesty and intelligence who shall open you the doors of Heaven?
