Law and Order

The local policeman had just finished his shift one hot August evening and was at home with his wife.

"You just won't believe what happened this evening, love, in all my years on the beat I've never seen anything like it."

"Oh dear, what happened?"

"I came across two lads down by the river, one of them was drinking battery acid and the other was eating fireworks."

"Drinking battery acid and eating fireworks!! What did you do with them ?"

"Oh that was easy, I charged one and let the other off."
