“Ghost Stories: April Fools Special” is a live comedy event currently running at UCB Theatre, where the familiar ritual of telling scary stories gets rerouted through prank logic and audience expectation. The show treats the ghost story as a performance form, using timing, misdirection, and confession to test what people will believe in a room together. In New York, that lineage runs from downtown storytelling nights to the city’s long habit of turning folklore into stage material. The best moments use the holiday’s premise to expose how easily sincerity can become a setup.
