100 Feet of What Now?
Sometimes examples of much-needed proofreading can exist right under your nose for years before you notice them. Case in point, here is the 1986 VHS box for the Ray Harryhausen extravaganza Jason and the Argonauts*, which I've owned for decades:

Look closer and you'll see a typo in the text that I hadn't noticed before, until my girlfriend caught it, four lines up from the bottom:

That's right, it's a "100-foot broonze giant"! I'm not sure what "broonze" is, but I'm guessing it's some kind of mixture of metal and alcohol. Way to go, RCA/Columbia Pictures Home Video! Remember, proofreading isn't just for internal memos and studio contracts anymore.
* Over the holiday, I showed my girlfriend two Harryhausen movies, The 7th Voyage of Sinbad, which isn't the best of the Sinbad movies in my opinion (that would be Golden Voyage) but does include the famous and awesome cyclops, and Jason, which she liked better and thinks she may have seen before. I also got to show her Psycho, which, to my surprise, she'd never seen before, and she loved it. She has good taste, even if she prefers Jason to Sinbad.
