If you want a good laugh: Stay late at work sometime and lower all the desk chairs to their lowest setting. Then get to work early to hear and see morning mahem.

If you want a good laugh, put laxatives in hamburger and feed it to your neighbor’s dogs, then blow a dog whistle and make your neighbors bring their dogs inside. Then watch for the carpet cleaners in their driveway the next day.
