"A lie will be half way around the world before the truth has got its boots on."
It's not hard to see why when people are how they are (to understand why people continue to do so is another matter entirely). I've taken to Snopes-linking all the rubbish that comes up on my Facebook from "friends". It's a brilliant way to deal with it because they either learn and stop posting nonsense or (more likely) take me off their friends list (which saves me the hassle and rudeness of doing so).
Everything from the "waiter's-missing-pound" maths puzzle, to junk about the brace-position on airplanes, to "medical" studies, to diets, etc.
The truth may be stranger than fiction, but fiction definitely has a better agency and gets more bookings.
