Actually I always thought a Misquotes site would be a really good sister site to Quotes.
The setup is key though, otherwise the dub will read the quote thinking it means what the wt is trying to say it means, then when they read the actual quote they will fool themselves into believing that the wt didn't actually say that.
I thought a neat little interactive would be key. Show a quote, offer a multiple choice list of what you actually think the quote means... then show the actual quote and ask what it really means.
There really are a ton of these. The trinity brochure, the blood brochure, the ante-nicene fathers....
