Costco has these REALLY GREAT Christmas decorations. Three white fir trees with softly lit (not) glass spheres. The spheres tastefully change colors and, as an added bonus to spread holiday cheer, the trees play a simple, synthesized glockenspiel version of the chorus of Jingle Bells (also known as the most repetetive Christmas song since Carol of the Drum).
Sadly, an inexplicably upset customer took it upon herself to crawl halfway into the shelf to turn off the power strip the trees were hooked up to. And would you believe it, she didn't even manage completely to stifle a manical laugh when a little girl hit the TRY ME button and nothing happened?!
