OK you can tell by the alliteration that police are a problem. This is a policeman and me having a conversation:
Police: Knock knock.
Me: who's there.
Police: it the police.
Me: john what did you do know?
Police: we just want to talk.
Me: were already talking!
Police: stop being smart with me you boy I need to talk to your guardian!!
Me: how many policemen are you?
Police: two.
Me: why don't you to start a conversation?
Police: can I come in?
Me: no
Police: I wasn't asking you!
Me: but that was a question, don't policemen know grammar these days.
Police: listen kid if you don't let me in I'll have to break through the door.
ME: THAT'S COOL YOUR A POLICEMAN YOU CAN AFFORD A NEW DOOR!!
