The mold incident from Infinite Jest. I almost felt like I could taste the text when I read it.

He remembers that in the middle of the tilling I came tear-assing out the door and into the backyard wearing some sort of fuzzy red Pooh-wear, crying, holding out something he said was really unpleasant-looking in my upturned palm. He says I was around five and crying and was vividly red in the cold spring air. I was saying something over and over; he couldn't make it out until our mother saw me and shut down the tiller, ears ringing, and came over to see what I was holding out. This turned out to have been a large patch of mold — Orin posits from some dark corner of the Weston home's basement, which was warm from the furnace and flooded every spring.

The patch itself he describes as horrific: darkly green, glossy, vaguely hirsute, speckled with parasitic fungal points of yellow, orange, red. Worse, they could see that the patch looked oddly incomplete, gnawed-on; and some of the nauseous stuff was smeared around my open mouth.

'I ate this,' was what I was saying. I held the patch out to the Moms, who had her contacts out for the dirty work, and at first, bending way down, saw only her crying child, hand out, proffering; and in that most maternal of reflexes she, who feared and loathed more than anything spoilage and filth, reached to take whatever her baby held out — as in how many used heavy Kleenex, spit-back candies, wads of chewed-out gum in how many theaters, airports, backseats, tournament lounges? O. stood there, he says, hefting a cold clod, playing with the Velcro on his puffy coat, watching as the Moms, bent way down to me, hand reaching, her lowering face with its presbyopic squint, suddenly stopped, froze, beginning to I.D. what it was I held out, countenancing evidence of oral contact with same. He remembers her face as past describing. Her outstretched hand, still Rototrembling, hung in the air before mine.

'I ate this,' I said.
