I'll start:

Once upon a time there was a beautiful princess named EEEK!!! Hide! It's HER!. EEEK!!! Hide! It's HER!'s father, the King, wanted to be sure his daughter married an intelligent man. To test his daughter's suitors the King hid EEEK!!! Hide! It's HER!'s picture in one of three boxes. The suitor had to be able to select the box with EEEK!!! Hide! It's HER!'s picture on one try and within twenty seconds. On the gold box was the message "Anna's picture is in this box". The silver box had the message "Anna's picture is not in this box." "Anna's picture is not in the gold box" was written on the bronze box. The King would tell each suitor "Only one of the three messages is correct." Which box contained EEEK!!! Hide! It's HER!'s picture?
