I've heard of it, too. The example I have in mind was getting an overly-broad subpoena that could be construed to include every sales receipt issued by the business over the last decade. These were delivered, unsorted and mixed in with other documents in a gigantic box, with "for attorney's eyes only" written on them, and bundled together with high-tension straps that would scatter the pages about the office when opened.

The parties settled and the documents were never touched.

I think that's a separate thing from what I was talking about, though you can certainly do both at the same time.
