Confuse them with praise!

I don't know what got into me. Was it the poodle skirt, the free fries, or perhaps I was just so far into the negative zone I had no where left to go. I started praising the kids in the hallway. I got some strange looks let me tell you. But rather than yelling "stop running, quit hitting, quit shouting..." I said "Thank you for your hallway behavior, your doing a great job". I know it sounds corny, but it let me not yell, and I was able to praise the kids doing their job.
I hope to pair it up with rewards after halloween. the kids might really go for that.
