Last letter to George Burns, as quoted in Two Minutes for God : Quick Fixes for the Spirit (2007) by Peter B. Panagore, p. 73; this was later used in a slogan for the United Church of Christ: "Never place a period where God has placed a comma. God Is Still Speaking."

"Black Squirrel on Cottonwood Limb's Tip" in Skyhook #23 (Winter 1954-55); re-published in Pearls From Peoria (2006)
Context: Oh, I'd reach beyond the comma of you
To the invisible phrase, the dangling Omega! No use. No act
Of mine or mind denies the ante-cerebellum fact
Of furry you, poised fleetingly, bright flex,
Black reflex, too leaping for me to ink and fix
As period to end what has no period, no, no
End...

Ring Around the Sun (1954)
Context: There was no time, Hezekiah had said. No such thing as time in the terms of normal human thought. Time was bracketed and each of its brackets contained a single phase of a universe so vastly beyond human comprehension that it brought a man up short against the impossibility of envisioning it.
And time itself? Time was a never-ending medium that stretched into the future and the past — except there was no future and no past, but an infinite number of brackets, extending either way, each bracket enclosing its single phase of the Universe.
Back on Man's original Earth, there had been speculation on travelling in time, of going back into yesterday or forward into tomorrow. And now he knew that you could not do it, that the same instant of time remained forever within each bracket, that Man's Earth had ridden the same bubble of the single instant from the time of its genesis and that it would die and come to nothing within that self-same instant.
You could travel in time, of course, but there would be no yesterday and no tomorrow. But if you held a certain time sense you could break from one bracket to another, and when you did you would not find yesterday or tomorrow, but another world.

The Years with Ross (Little Brown & Co, 1957, pg.267)

Variant: From one casual of mine he picked this sentence. “After dinner, the men moved into the living room.” I explained to the professor that this was Ross’s way of giving the men time to push back their chairs and stand up. There must, as we know, be a comma after every move, made by men, on this earth.

Memo to The New Yorker (1959); reprinted in New York Times Book Review (4 December 1988); Harold Ross was the editor of The New Yorker from its inception until 1951, and well-known for the overuse of commas
