"The sun oozed over the horizon, shoved aside darkness, crept along the
greensward, and, with sickly fingers, pushed through the castle window,
revealing the pillaged princess, hand at throat, crown asunder, gaping
in frenzied horror at the sated, sodden amphibian lying beside her,
disbelieving the magnitude of the frog's deception, screaming madly,
"You lied!"
