My friend Jason and I accidentally invented this game while at a party last week. The rules are simple:
1. Make an observation about a particularly odd aspect of human behavior.
Example: "Why is it that everyone congregates in the kitchen at parties, even when there's plenty of space elsewhere?"
2. Come up with an explanation for how that behavior would have increased fitness in hunter gathering societies.
Example: "Well, food used to be sparse, so humans would congregate at food sources, so you'd be more likely to find a mate there, and thus have more babies.
3. Bonus points are rewarded for including 50's era gender stereotypes.
Example: "Well, we KNOW women are drawn to the kitchen because they're inclined to gather food, so they're always in the kitchen anyway. The men just go there to be around their potential mates."
Hours of fun guaranteed.
