A system administrator I knew at HP Labs, Mike Rodriquez, named his personal workstation "walstib."  Mike explained that it was an acronym for "What A Long, Strange Trip It's Been," which, he said, was a kind of motto among Deadheads.  (I gather it's a line from one of the many indistinguishable Grateful Dead songs.  Sorry, Mike.)
