A little boy went to his teacher to tell her he found a frog.
The teacher asked if it was alive or dead.
The little boy said that it was dead.
The teacher asked how he knew.
The boy said , "I pissed in its ear."
The teacher said, "You what?"
He said, "You know, I went to his ear and said, 'psst!' and it didn't move. So it must be dead."
