Researchers recently tried to determine the world’s funniest joke. And then they crunched numbers to find what was the funniest time of the year. Sure – maybe the biggest joke of all is the idea that scientists thought they could pin down what funny is. “There may be no more subjective art. One man’s glee might be another man’s unforgivable insult. Men and women often diverge wildly over what makes them laugh. Age, too, creates gulfs. Geography dictates still more patterns of comic appreciation.”
