A group of youths took eggs to a Turkish bath where Nasrudin was expected.
   When he came into the steam-room where they were sitting, they said: ‘Let is
imagine that we are fowls, and see whether we can lay eggs. The one who fails 
shall pay the bath fee for all.’
   Nasrudin agreed.
   After a little cackling, each one took an egg from behind him and held it out.
Then they asked Nasrudin for his contribution.
   ‘Among so many hens,’ said Nasrudin, ‘there will surely be one cock.’
