Thomas and his colleagues maintained the mishap was the result of a scientific experiment to investigate whether LSD brought on an unusual condition in which elephants become aggressive and secrete a sticky fluid from their glands. In a report of the incident submitted to the US journal Science four months later, the team concluded: "It appears that the elephant is highly sensitive to the effects of LSD."

That's one thing the elephant is sure not to forget.
