A kindergarten teacher had a pupil tell her he'd found a frog.

She asked whether it was alive or dead.

"Dead," she was informed.

"How do you know?" she asked.

"Because I pissed in his ear," said the child innocently.

"You did what?" said the teacher in surprise.

"You know," explained the boy, "I leaned over and went PSSST in his ear, and he didn't move."
