Smith Magazine’s six-word memoirs have been lodged in the literary firmament since the 2008 release of “Not Quite What I Was Planning,” a pocket-sized collection that became a bestseller. The idea of a story in six words was inspired by an Ernest Hemingway legend — he is said to have won a bet about writing a short story in just six words with “For sale: baby shoes, never worn.”The latest book in the six-word memoir series, “It All Changed in an Instant,” is out now. It contains hundreds of micro-mini memoirs from people unknown and known. Smith got several people you’ve heard of — including Junot Diaz, Malcolm Gladwell, Sarah Silverman, Art Spiegelman, Molly Ringwald, Margaret Cho, and Tony Hawk — to give it a go.Of those that appear in the promo video above, James Frey’s stands out.

For his six-word memoir, Frey writes: “So would you believe me anyway?”
