A nursery school pupil told his teacher he’d found a cat, but it
 was dead.
‘How do you know that the cat was dead?’ she asked her pupil.
‘Because I pissed in its ear and it didn’t move,’ answered the child
 innocently.
‘You did WHAT?’ the teacher exclaimed in surprise.
‘You know,’ explained the boy, ‘I leaned over and went ‘Pssst’ and it
 didn’t move’
