If memory serves me - Arnold the pig somehow submitted an entry for a contest where the winner gets a trip to Hawaii. After Arnold won, the contest sponsors did not want him to go (they wanted a person, not a pig). This case went to court, and Arnold won the right to go to Hawaii. But in the end - Arnold chose not to go. - one of the events in Hawaii was a Luau with a roasted pig :) Maybe that's a spoiler - but for a show from the 1960s.. (And it's in the title of the show).
