A teacher had a 5-year-old come up to her and say that he had found a frog.

The teacher asked, "Is the frog alive or dead?"

The student replied, "It's dead."

The teacher asked, "How do you know for sure?"

The boy said, "I pissed in its ear."

Aghast, the teacher said, "You did what?"

He said, "You know, I went to his ear and said, Psst and it didn't move. So, it must be dead."
