What's the worst speaker or stereo set-up you've ever seen?

I used to do home delivery and installation work and had access to some pretty high-end homes. I was amazed at how few of these well-heeled owners had nice audio systems, although many had some nice home theaters. One home owner had a basement stereo with small Maggies hinged on a wall like cabinet doors so he could direct the sound and, I guess, tuck them away when not in use. I also saw a pair of Bose 901’s pointed the wrong way. What’s the worse set-up you’ve seen?
