Below is roughly as I recall from him telling the story. Olin has a colorful sense of humor (see his usenet posts).
The anti-acknowledgements page was originally intended for his doctoral thesis. It was going to contain everyone who discouraged or otherwise hindered his efforts to degree (e.g. parents, girlfriend). His advisor talked him out of it.
Later when he was at the one of MIT's lab he puts in the SCSH manual. The manual gets printed and distributed. He doesn't hear anything. Later he gets called into the head of the lab's office. Olin comes in and sits down. The director takes out the manual and opens it to the acknowledgements section. The first question is "Who has been stealing your work?", the second one is "do you need to go into rehab?". Olin tells him it's a joke. It ended up being a career limiting move for him.
