I feel so vindicated. For years I've railed against this stupid scene in Goodfellas, explaining that it doesn't work in the first place and all chopping your garlic that slowly does is give it lots of time to oxidize and turn gross. Well I just heard a clip of Jimmy Kimmel talking about asking Scorsese about how to do it because he'd been trying for years. To which Scorsese told him it doesn't work, it's just made up bullshit for a movie.
Any other good examples of false things like this that became memes?
