This one definitely belongs in the number 1 spot. What do you normally do when you have a dispute? Do you talk things over? Go to court? Well, in New Guinea, to settle disputes, the people rely on biritululo. Biritululo is the act of comparing yams (and I am hoping that is meant in the literal sense) to settle a dispute. The closest we come to that in English is too rude to post on listverse, but it is also involves comparing something similarly shaped (but not sized unless you are extraordinarily lucky).
