Self Incrimination

Me - What are you doing?!?!?
Thing #1 - Nothing
Thing #2 - What he said....
Me - I want an explanation right now!
Thing #1 - Were grounded aren't we?
Thing #2 - Nooooo, he doesn't know we were choking each other!
Me - No, I didn't, why don't you tell me now.
Thing #2 - How long am I grounded for?

I still dont know why they were fighting and no one is talking!
