There's loads of stuff on the Internet about mistakes, lots of it funny and some of it even true. Below is a sampling, but you can find more on my blog—or, better yet, send me video, photos or links to your favorite mistakes. If I mention them in my blog, I'll be sure to give you credit. DotheTest.co.uk—For great examples of visual errors, try this link for an ad campaign by Transport for London. Visual Cognition Lab—The ads (above) follow the groundbreaking research of Professor Dan Simons, whose own videos and research can be found here. RegretTheError.com—A great repository of newspaper corrections. One of my favorites is the belated (by 100 years) correction of a story on the famous first flight of the Wright Brothers. Another gem, this one from the U.K.: "Following the portrait of Tony and Cherie Blair published in 21 April in the Independent Saturday magazine, Ms. Blair's representatives have told us that she was friendly with but never had a relationship with Carole Caplin of the type suggested in the article. They want to make it clear, which we are happy to do, that Ms. Blair "has never shared a shower with Ms. Caplin, was not introduced to spirit guides or primal wrestling by Ms. Caplin (or anyone else), and did not have her diary masterminded by Ms. Caplin." You Tube—See the hilarious Trailer Park Boys video on the perils of "self smarting" ourselves. It's a parable for all you do-it-yourselfers out there. MichaelBach.de/ot—For visual mistakes of all kinds, see the website of Michael Bach. In particular, check this one out. Idolator.com—To see just how easy it is to forget things we ought to remember, go to the "Hey, it's Enrico Pallazzo!" Hall of Fame section to watch Michael Bolton muff the words to the National Anthem.
