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.

You did WHAT?' the teacher exclaimed in surprise.

'You know,' explained the boy, 'I leaned over and went 'Pssst' and it didn't move'

'it was ten mnutes before the teacher could stop laughing enough to resume the glass.'
