Fetishes on Parade

In September, police in Bonney Lake, Wash., were seeking "Dale," who had been reported hanging around the high school, trying to befriend male athletes. In the most recent incident, he lured a boy to the library, offering help on a term paper project, but when the boy declined and walked away, "Dale" jumped on his back and asked for a piggyback ride. (Fondness for piggyback rides is not a widely practiced obsession, though the legendary illustrator R. Crumb liked to receive them in lieu of sex, according to an ex-girlfriend in the 1994 movie "Crumb.")
