I feel like egging a KH or trashing one - I got to get some tea.
I have felt like decorating one for Christmas. If I had the money to waste on decorations that would be thrown out and felt certain that I would not get caught, I would make a trip to Wal-Mart. Once there, I would go out and buy about 50 garlands in the 60 foot length, as many lights and inflatables as I could get, some sleighs and reindeer, icicle lights in the length of the perimeter of the whole Kingdumb Hell, candy cane lights for the walkways, a 4 foot wreath with lights, a Christmas tree for the lobby and another one for the platform (where the podium would normally be), and as many smaller ornaments as possible to decorate the Kingdumb Hell with.
Then I would go in and put hooks right in the wall for all the garlands. The whole perimeter of the Kingdumb Hell would be decorated with garland, as would the perimeters of all the windows. They would be lit with 5 or 6 layers of lights. I would also put candles in all the windows (the electric ones). The lobby would have its chandelier bulbs replaced with red and green ones, and every kind of Christmas decoration including mistletoe in every possible place. The Christmas trees would go up, complete with lights and as many bulbs and garlands (and religious ornaments) as I could get.
With the inside done, I would then put the garland, wreaths, and lights outside. Every possible place for lights would be lit, including every bush. Candy canes would go up along the walkway. There would be a huge Nativity scene on the front lawn. On the roof would be a Santa sleigh with reindeer, totally lit up. Snowmen would be lit on the front lawn in a different section. I would have a smooth transition from the Nativity scene to more traditional Christmas decorations and inflatables along the whole property. Of course, I would set it up so they would have a miserable time trying to take it all down.
I wonder how many boasting sessions would be cancelled while they are working on taking it down.
