Just for the benefit of new players.... as described by @Rikand - the Chewbacca Rule:
Quote:When presented with a question such as :: Name a non-human character in star wars, the 3 most obvious answers are :: R2D2, C3PO and Chewbacca
The elite play is to pick R2D2 because the other two selections both begin with C and therefore there could be a split of people picking those which would halve the potential score of the sheep. Hence why its called the Chewbacca rule. Because you should always pick the letter answer that only has one possible answer and not the letter answer that could be split.
