Fun Fact: “It’s elementary, my dear Watson” was never said in any Sherlock Holmes book written by Sir Arthur Conan Doyle.

Other Misquotes: “My Momma always said life is like a box of chocolates – you never know what you’re gonna get.”
(It’s not a real misquote, but it was never said in the original)

“Luke, I’m your father.”

And, of course, you can’t forget “etcetera.”

…As in, there are more. That’s not an actual quote. To my knowledge.
