At Eureka Day School in Berkeley, all decisions are made by consensus, diversity and inclusion are valued, and vaccinations are a personal matter. When a mumps outbreak hits the school, it turns out that not everyone in the community has the same definition of social justice. Now the board of directors must confront the central question: how do you find consensus when you can’t agree on the facts? A comedy for our moment!

Lead Underwriter: Marvin F. Weissberg

DC Theater Scene

"... a master class in tight ensemble acting."

"a roll-in-the-aisles funny exhibition of adults behaving badly."

DC Metro Theater Arts

"Eureka Day of the funniest plays to open this year"

The New York Times

"Jonathan Spector’s lively portrait of a debate over mandatory vaccinations is the perfect play for our age of disagreement."

The New York Times

"Uproarious! Jonathan Spector's play is so crisply defined that you might have to periodically remind yourself that you haven't already met these characters in real life..."

San Francisco Chronicle

"So brilliantly yoked to the current American moment... that it makes you want to jump out of your skin... Electrically funny."
