Just in case you're wondering, the string "polygenelubricants" traces its origin to Java Puzzlers by Joshua Bloch and Neal Gafter; it is a string whose hash code in Java is
Integer.MIN_VALUE. It was used to demonstrate a corner case involving the most negative number in a two-complement representation.
Going for the classic may not have been terribly original, but I think that's also precisely why it's the right choice. Lest I be accused of merely stealing other people's work, however, I will list more strings that fall into the same bucket. The first 4 of these are already known; the rest are my own discoveries.

While we're at it, I also found some examples of the equally (if not more) important strings that hash to 0.
