I had two words I thought of; one was Urinetown, a musical, my son and I saw several years ago. The thing I remembered the most about it was we liked it and it was good but nothing else about it ;-) The second word was Undertaker. I don't have much to say about this either but that's what I chose, ha!
When I went to elementary school, one of the girls I went to school with her father was an undertaker. They lived upstairs from the funeral home. The few times I went to go visit her, I had to ring a doorbell that led into a hallway. Then I would go up a flight of stairs to where they lived. When I would go up those steps, there would be a door off to the side. I always felt uneasy and unnerved when I would see that door. I always thought that was the door to where they did the embalming which was probably unlikely but I was a kid so what did I know.
That's about all I have to say on that unpredictable, unexpected, and unique subject.
