There’s a tome one may still be able to track down a copy of called “The Meaning of Lost and Mismatched Socks” by one “Dr. Perditus Pedale, M.D. PH.D” which may shed some light on this phoenomenon. Illustrated by none other than underground cartoonist Dr. Harry (Hal) S. Robins, voice of Dr. Kleiner in Half-Life and famed SubGenius radio minister.
