I was flipping through a 1980 magazine I believe published by LFL in 1980 called the Empire Strikes Back 'Collectors' Edition' Magazine. (Here's the cover) I noticed on the spread that explains the Bounty Hunters that Zuckuss is actually referred to as Zuckass. I wonder if that's true? Maybe it was the original name of that character and it had to be toned down due to the ... um... insinuation. Or it could be a typo I suppose.
