I've highlighted several things in @pluralistic@mamot.fr 's Picks and Shovels, but one short sentence fragment I especially like is:

using a ream of his virginal fanfold printer paper

which alludes to the protagonist's earlier dumpster diving activity to find discarded tractor feed paper that had only been used on one side.

Although I never actually dived a dumpster for half used printer paper, I do remember scavenging long sections of such paper from computer room garbage cans, back in the day.
