Please, someone help my stupid neighbour

I am extremely concerned about my neighbour (the laughing policeman for those interested). He has been emitting the strangest, strangulated hoots for over an hour now and my unofficial diagnosis is that he is now hysterical due to being in the final stages of his stupidity consuming him whole. A sort of 'silly'fication if you will. The process has obviously reached his ears already because no mortal would be able to tolerate the sound of such thickery coming out of their own mouths without shutting up. 

If you have experience in working with such unfortunate people, or are just very big and very violent, please do all you can to put him out if his misery. And mine.
