I was once working on the crew for a sizable music event, and was inadvertently shpongled (I had knowingly administered, but was surprised by the strength of the material). At one point two police officers showed up to check things out, and they shined their flashlight and yelled inside the venue for someone to come out and talk with them. I'm usually very good at this, communicating with authorities, so I went out to them. I approached them and smiled, then tried to speak, but realized that I was so high, like up there by the stratosphere, that I was unable to communicate at their level. I understood what they were saying, but simply was unable to formulate a response, and stuttered multiple times while trying to respond, but did it with a smile. I then started to try to speak in sign language to the people inside the building, motioning for them to send someone else outside.
Soon the main organizer came out, and the police started to yell at him about "noise and building infractions", blah blah blah, so I just looked on and smiled. I think about 10 seconds later they realized we were "good-natured" or whatever and cooled down, just explained people needed to stay inside so the neighbors wouldn't be disturbed (said they had better things to do and didn't want to be called, city cops are usually like that I find). So I translated between the officers and the organizer and the people inside, using improvised sign language, motioned for them to close the door and head inside, and to keep everything "cool", and they sort of telepathically followed along, headed inside. The doors closed, the officers left, and I headed back inside.
