While in high school (mid-90s), I read a collection of short stories. One story in the book was "Buckets" by F. Paul Wilson.
Another story was about two mechanics, working on a feed grinding machine at a hog farm. One guy is inside the machine and the other guy turns it on, not realizing the first guy is in it. Literally half-mangled, the guy inside the grinder convinces the other guy that the pain is wonderous, and to turn it back on so he can finish himself. For some reason, the other guy also goes into the grinder while it's on to kill himself (maybe to feel the wonderous pain himself??).
Those are the only two stories in the book I remember, though there were others. I don't think they were all by Mr. Wilson, but I could be wrong on that. I was recently asked about the book, and would like to find the title so I can buy it and enjoy it again.
If anyone can help me, I'd truly appreciate it! Thanks!
