I just finished reading this great book on cartoonist Virgil Partch, who defined cartoon weirdness for several decades.
The book revealed that Partch was a great joker in real life as well. He and some buddies founded the Balboa Island Sculling and Punting Society, which was an excuse to putter around the marina, freak out the squares and get drunk. Not satisfied with those activities however, they aimed higher. First they decided to take a "boat ride" from their West Coast hangout to Las Vegas. How? By putting a boat on a truck and riding inside the craft while being driven across the desert.
Then they decided to take a train to Catalina Island, by a similar expedient.
Adam Purple is an activist and urban Edenist or "Guerrilla Garderner" famous in New York City from the seventies to the present day. His name at birth was David Wilkie, though he's gone by many others, including the Rev. Les Ego. He is often considered the godfather of the urban gardening movement, and his "Garden of Eden" was a well-known garden on the Lower East Side of Manhattan until it was demolished after considerable controversy, extending from the Koch Administration through the Dinkins Administration by then mayor Rudolph Giuliani...
The image of Adam Purple familiar to New Yorkers in the seventies and eighties was of a man wearing at least one article of purple clothing, and with a thick graying beard, riding a bicycle through Manhattan streets and scooping up manure left by hansom cab horses, which he used to fertilize his urban garden.
