I mouse over the upvote icon. My finger twitches involuntarily as I think of my mother singing. My mother drops a dish, which shatters into a handful of corners of the room. The corners collaborate. Their consensus is angry, and my argument is invalid. A jury of my peers deems me a collection of disappointments. I am allowed a drink of water. A fountain asks me whether I've heard of my mother. I respond in the negative. A jury of my peers deems me a fraud. My mother names a fountain in my honor.

7 Cuils: riverrun, past Eve and Adam's, from swerve of shore to bend of bay, brings us by a commodius vicus of recirculation back to Howth Castle and Environs. Sir Tristram, violer d'amores, fr'over the short sea, had passencore rearrived from North Armorica on this side the scraggy isthmus of Europe Minor to wielderfight his penisolate war: nor had topsawyer's rocks by the stream Oconee exaggerated themselse to Laurens County's gorgios while they went doublin their mumper all the time: nor avoice from afire bellowsed mishe mishe to tauftauf thuartpeatrick: not yet, though venissoon after, had a kidscad buttended a bland old isaac: not yet, though all's fair in vanessy, were sosie sesthers wroth with twone nathandjoe.

The fall (bababadalgharaghtakamminarronnkonnbronntonnerronntuonnthunntrovarrhounawnskawntoohoohoordenenthurnuk!) of a once wallstrait oldparr is retaled early in bed and later on life down through all christian minstrelsy. The great fall of the offwall entailed at such short notice the pftjschute of Finnegan, erse solid man, that the humptyhillhead of humself prumptly sends an unquiring one well to the west in quest of his tumptytumtoes: and their upturnpikepointandplace is at the knock out in the park where oranges have been laid to rust upon the green since devlinsfirst loved livvy.

An example of a statement that has a sinusoidal Cuil function.
You are the bread and the knife,
You are the bread and the knife,
the crystal goblet and the wine.
You are the dew on the morning grass
and the burning wheel of the sun.
You are the white apron of the baker
and the marsh birds suddenly in flight.
However, you are not the wind in the orchard,
the plums on the counter,
or the house of cards.
And you are certainly not the pine-scented air.
There is just no way you are the pine-scented air.
It is possible that you are the fish under the bridge,
maybe even the pigeon on the general's head,
but you are not even close
to being the field of cornflowers at dusk.
And a quick look in the mirror will show
that you are neither the boots in the corner
nor the boat asleep in its boathouse.
It might interest you to know,
speaking of the plentiful imagery of the world,
that I am the sound of rain on the roof.
I also happen to be the shooting star,
the evening paper blowing down an alley,
and the basket of chestnuts on the kitchen table.
I am also the moon in the trees
and the blind woman's tea cup.
But don't worry, I am not the bread and the knife.
You are still the bread and the knife.
You will always be the bread and the knife,
not to mention the crystal goblet and — somehow — the wine.
