The Rhinoceros Party of Canada

Wikipedia:

The Parti Rhinocéros, commonly known as the Rhinoceros Party in English, was a registered political party in Canada from the 1960s to the 1990s. Operating within the Canadian tradition of political satire, the Rhinoceros Party's basic credo, their so-called primal promise, was "a promise to keep none of our promises." They then promised outlandishly impossible schemes designed to amuse and entertain the voting public.

The party claimed to be the spiritual descendants of Cacareco, a Brazilian rhinoceros who was elected member of São Paulo's city council in 1958, and listed Cornelius the First, a rhinoceros from the Granby Zoo, east of Montreal, as its leader. It declared that the rhinoceros was an appropriate symbol for a political party since politicians, by nature, are "thick-skinned, slow-moving, dim-witted, can move fast as hell when in danger, and have large, hairy horns growing out of the middle of their faces."

Some members of the Rhino party would call themselves Marxist-Lennonist, a parody of the factional split between the Communist Party of Canada and the Communist Party of Canada (Marxist-Leninist), although the Rhinoceros Party meant the term in reference to Groucho Marx and John Lennon.
