If women ran the world we wouldn’t have wars, just intense negotiations every 28 days.

Framed as a comic counterfactual, the line riffs on a familiar stereotype: that women would be less inclined toward armed conflict and more inclined toward verbal bargaining. The punchline hinges on “every 28 days,” an allusion to the menstrual cycle, turning a utopian premise (“no wars”) into a joke about periodic, heightened tension expressed as “intense negotiations.” As with much of Robin Williams’s stand-up, the humor comes from rapid juxtaposition—idealism undercut by bodily reality—while also revealing how gendered assumptions about emotion, aggression, and leadership circulate in popular culture. The joke can be read as both a satirical critique of male belligerence and a reliance on reductive biological humor.
