I didn't see this topic when it first came round, but now Modulous Prime has pointed me here, I thought I'd explain mine too.
Its the name of an elephant who was administered a very large dose of LSD to see if it would provoke
musth. He died a pretty unpleasant death, unfortunately. The tale might be apocryphal, I don't know - but if it did happen it was in the 60s.
The story (just google Tusko LSD) is sad and leaves you wondering what the scientists were thinking. It somehow seemed appropriate for a science forum.
