How about a toilet anchored to the floor of a teachers lounge bathroom by the Sloan valve? I just had a job yesterday where a DIYer installed all the plumbing in his new construction home. The shower leaked thru the ceiling. I discovered the previous brain sturgeon used the rubber washer for the shower drain under the flange, instead of putty, and nothing on the locknut. Then to make it worse, he put all kinds of backing where it wasn't needed; to make it all but impossible for me to repair it without major ceiling removal. I got it though. His dad was there to let me in, and I made a friend for life. He thought I would have to destroy the ceiling in order to save it. My mad skilz amazed him.
