"Nourished on the blood of a schizophrenic, a spider weaves crazy webs."
-Guido Ceronetti, The Silence of the Body
During the 1950s, a swiss pharmacologist named Peter Witt conducted a set of experiments in spider doping. He found that the spiders spun uniquely cockeyed webs depending on which substance they had ingested.
