The Rhinoceros Party of Canada
For 30 years, the Rhinoceros Party was a recognized political party within Canada. Although it was a joke party, it's members have ran as official candidates in many MP and Prime Minister elections.
Some of the campaign stances of the Rhinoceros Party include:
One member, Alfred the Alien, ran in the 1988 Prime Minister elections. He had a number of interesting policies.
They have never won any elections, but have still consistently gained a considerable amount of votes. From the looks of it, they usually get 50,000-100,000 votes in the federal elections for Prime Minister. And in the past, the Rhinoceros Party has actually come in second place in MP elections, beating 2 out of Canada's 3 main political parties.
