"When you can't decide on something, but it has to be decided, you usually settle it through chance. One of the ways of deciding things by chance is that you take as many straws as there are options, cut one of them shorter or longer than the others, and have an impartial party hold them in their fist so you can't tell which one is the odd one out. Then everyone who's arguing draws a straw. The person who gets the odd straw out either wins or loses depending on what kind of argument it is."
