Some years ago my son and his friend were playing an early Adventure on a TRS-80. The jewels to be collected were in a throne room at the edge of a cliff and the room was guarded by a bear. Using all the various tools, weapons, and spells at their command they were unable to get rid of the bear. This went on for some 20 minutes or so. Finally in frustration they entered: "Fuck bear!" The program's response was: "Bear is so startled it falls off cliff."
