In Response To: 100 islanders logic puzzle (bob koca)

Ten people with blue eyes kill themselves. Each person looks at everyone else and counts 10 with blue eyes...unless he can count only nine with blue eyes, in which case he knows that he must be the tenth person with blue eyes and therefore must kill himself.
