A soccer hooligan is charged with disorderly conduct and assault after a match. The arresting officer states that the accused had thrown something into the river not far from the stadium.

“What exactly did the accused throw into the river?” the judge asks.

“Stones, sir,” the officer replies.

The judge is confused. “Well, that’s hardly an offense, officer.”

“It was in this case, sir,” the officer explains. “Stones was the name of the referee.”
