Perhaps the most famous piece of very short fiction is the story Ernest Hemingway apparently considered his best prose:
"For sale: baby shoes, never used."
Like most things Hemingway, the few words expand into a massive picture in one’s mind. A real work of art and, in this case, very sad.
My favorites are:
“Failed SAT. Lost scholarship. Invented rocket.”
– William Shatner
“Machine. Unexpectedly, I’d invented a time”
– Alan Moore
“Internet “wakes up?” Ridicu –
– Charles Stross
For those that remember actually needing a carrier signal.
“It’s behind you! Hurry before it “
– Rockne S. O’Bannon
“Easy. Just touch the match to”
– Ursula K. Le Guin
Loads of fun ones. Check ‘em out.
