Oz discussion

The Wicked Witch has taken the oil. She will let you take it once to save the tin man if you solve her riddle. Solve it before the tin man rusts! Then you must give her back the oil and she will give you another riddle. A mod will post a riddle and give a due date for solving it: when the tin man rusts. If the tin man rusts, no one will be allowed to play games for a day.
