The Bathroom
From KGB Wiki
Truly, a horrific site, you bear witness to the most horrific things. Mankind was not meant to know such horror, yet you glimpsed but a fragment of true evil. Not even Death will release you from the things you have seen, they will haunt you forever. Your final sane thought is "What kind of person would install a TV in a bathroom playing a Barbara Streisand show on a loop!?!?"
