Very short stories...

The most recent Wired magazine has an amazing bit titled "Very Short Stories: 33 writers, 5 designers. 6-word science fiction." It is worth buying the rag for it (and the aethiest article is a plus, too). I offer my favorites as a taste:

Vacuum collision. Orbits diverge. Farewell, Love. -- D. Brin
machine. Unexpectedly, I'd invented a time -- Alan Moore
Gown removed carelessly. Head, less so. -- Joss Whedon
"Cellar?" "Gate to, uh... hell, actually." --Ronald D. Moore
Longed for him. Got him. Shit. -- Margaret Atwood
From torched skyscrapers, men grew wings. -- Gregory Maguire
Internet "wakes up?" Ridicu- No Carrier. -- Charles Stross
The baby's blood type? Human, mostly. -- Orson Scott Card
Lie detector eyeglasses perfected. Civilization collapses. -- R. Powers
Husband, transgenic mistress; wife: "You cow!" -- Paul Di Filippo

Arguably the best is, of course, by Vernor Vinge:

Epitaph: Foolish humans, never escaped Earth.

My second favorite is less a "story" than a powerful quotation, "It cost too much staying human." (Bruce Sterling)
