When I was younger, I did this at K-Mart "2. July 2: Set all the alarm clocks in Housewares to go off at 5-minute intervals." but I did them all at the same time. Also, got a cart full of expensive stuff and put it under the "blue light sale" K-mart used to do. Finally we made a wall of the water cases across the aisle. lol About 80% through my wall they kicked me and my buddy out.
