Ohh, so many to choose from... hmmm; well; I suppose the chicken did, alphabetically speaking... in English that is...
Chronological word/sound formation-wise? No clue, but I'm sure it can be searched, to possibly satisfactory approximation.
In terms of biologically active, elemental material; perhaps one must consult both the "chicken", and the "egg", separately; and then together; because both are unknown potential liars, that we can never fully trust anyways.
When it comes to perceptually symbolic references; one might consider visiting "the void", and contemplating the concept, of experiencing a linear progression of events, "contained" within an all present now-ness of no-time.
When there are too many of either to count; not enough to go around; or a short-circuiting, internal process loop; in lieu of such a magnanimous preponderance... and it's becoming an issue; one might benefit from shifting focus back towards awareness of the body's natural breathing pattern, and that perhaps, partaking in such things, may not be in one's best interest.
When it comes to came, it approaches already occurred, until it reverses in on itself, in a strange, double overlap, of auto-redundant, invertitude; at which point, both chicken and egg, de-materialize, implosionally; and one pops back to, in a plant-life based, poorly lit ass, setting-like place; with peculiarly posture-ating, peoples of paint-faced proclivitid-ness... proclaiming the power of pea-pie-poo, and the chicken egg stew; dem done came full circle... cock-a-doodle doo... The End... Beginning.
