A woman summoned the Mulla in his capacity as a physician,
because she did not feel well. When he arrived and tried to take
her pulse, she was too shy, and covered her arm with her sleeve.
   Nasrudin took a handkerchief from his pocket and laid it on
the sleeve.
   ‘What are you doing, Mulla?’
   ‘Didn’t you know? A cotton pulse is always taken with a silken hand.’
