Sinister: I Can Only Give Chu Everything (Features plausibly exciting picnic details)

[The Boy G]

THE RIDDLE:
100 prisoners in solitary cells. There's a central living room with one
light bulb; the bulb is initially off. No prisoner can see the light bulb
from his or her own cell. Everyday, the warden picks a prisoner at random,
and that prisoner goes to the central living room. While there, the prisoner
can toggle the bulb if he or she wishes. Also, the prisoner has the option
of asserting the claim that all 100 prisoners have been to the living room.
If this assertion is false (that is, some prisoners still haven't been to
the living room), all 100 prisoners will be shot for their stupidity.
However, if it is indeed true, all prisoners are set free. Thus, the
assertion should only be made if the prisoner is 100% certain of its
validity.

The prisoners are allowed to get together one night, to discuss a plan. What
plan should they agree on, so that eventually, someone will make a correct
assertion?

This is a gorgeous riddle.

THE SUN-COMPREHENDING LASS:
I caught self-consciousness from Erica MacArthur, you know. Andrew Churchman
would approve.

THE NERVE.COM PERSONAL AD:
Goes like this - "Because I'll be the private-school eye-candy that you
think you want. Because I'll tell you pretty lies, and refuse to slow-dance.
Later on, we'll have realised that it was never going to work, but the
letters we'll send will embarass your future boyfriends."

No-one replies.

THE QUOTE:
"Yeah. Yeah, that. It's quite saucy! Superb..." - Ken Chu, asleep on
Marianna's sofa.

THE BIG IDEA:
August 10th - Official Boy G leaving picnic. 2pm, Primrose Hill or Spread
Eagle if raining. Bring presents, the answer to the riddle, or just bring
yourselves, yo. Strange Fruit will follow, the beginning of everything else.
August 11th - All new Archel-confirmed rearranged Brighton shebang! It's a
one-day festival of piers, poets and pebble beaches. You really ought to go.
August 13th - G flees from shame of humiliating picnic behaviour, gets on
plane. Arrives Charlotte, meets the Llew, collapses and dies at tragically
young age having acheived all remaining ambitions.
