Character in the novel So Long, and Thanks for All the Fish
by Douglas Adams
. After reading the instructions
on the back of a box
(instructions on a box of toothpicks?!) he decided the world
and built an asylum
to put it in.
His asylum was basically an inside-out house. He lived on the outside (inside) with his wife, Arcane Jill Watson, because they were sane. The rest of the world lived on the inside (outside) because they were not.
Wonko (real name: John Watson) often went for long walks on the beach, where he was joined by angels wearing Dr. Scholl's orthopedic sandals.
