Battery Acid and Fireworks

A local policeman had just finished his shift one cold November evening and was at home with his wife.

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

- Oh yes dear, what happened?

- I came across two guys down by the canal, 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.
