Sheppard's Law
http://trickster.org/speranza/cesper/Sheppardslaw.html

"Murphy's law," John blurted. He knew he should be afraid, but he just felt numb. "Anything that can go wrong, will go wrong: they're just waiting for something to kill me."

"Weird? You don't know what weird is. Weird is being in a-- with the-- and the crazy alien--" He stopped, incoherent, hands flailing. "And then your best friend is twelve, and you're his piano teacher. That--now, you're talking weird!"

"Weird? You don't know what weird is. Weird is being in a-- with the-- and the crazy alien--" He stopped, incoherent, hands flailing. "And then your best friend is twelve, and you're his piano teacher. That--now, you're talking weird!" [SGA, McKay/Sheppard, 34,472 words]

Quantum Leap, SGA style: When aliens punish John by disrupting his timeline, Rodney has to travel back in time (over and over) in order to save his life (over and over). Forty years of John in 40,000 words.

Author's Note: This is the story of...John Sheppard's whole life, and it takes about forty years to tell. *facepalm* No, seriously; I apparently need to keep building John up from scratch.

So inside the box, the cat is gay and not gay at the same time--"
