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

Maybe 25 yrs ago.  A good friend of mine at the time had me over to listen to his brand new Legacy Focus.  The speakers were visually stunning.  But he had them running with a pair of HK 100 wpc monoblocks that made them sound like there was a mattress between the speakers and me.  All I heard was a giant midrange.  No highs, no lows.  Totally sucked, which was a shame because he had the right room size for those speakers.  Needless to say, he got some real amps for those speakers after that, but he moved to another state.  So I never got to hear them again. 

At another and more recent gathering,  the wife and I went to her friend's house with whom she had recently reconnected.  The friend and her husband hosted a pretty nice party in the back yard.  Pool, outdoor kitchen, covered patio, the whole sha-bang.  They had music playing that was so loud and distorted that i had to see what equipment was hiding in the racks and what speakers were hanging from under the patio eaves.  They were Bose outdoor somethings being pushed by a decent Yamaha receiver.  The funniest of all this was that the guy who designed the patio and chose and installed the audio gear was there and was bragging about how long it took him to get the sound just right and couldn't believe how good "it still sounds".  Wake up doooood.  Complete garbage sounding.
