On the main screen (with the world view in the middle and the character portraits on the right), click on any character portrait (except the main character) 9 times in succession (which one would not normally do). Now, the next few times you click on that character's portrait, they will say unusual and funny things. For example, one of the wizardess Dynaheir's sayings is, "These boots are made for walking, and that's just what they'll do." Another example, the fighter Khalid (who stutters) says, "Click on someone your own size!" and "Ch-ch-ch-ch-chia!" (As in Chia Pets.)
