Five women storm the stage. Over the loudspeaker Philadelphia-bred rapper Khia sings of her neck and her back and two specific parts of her nether regions while the ladies hump the air and pound the walls—one even does a handstand. They’re Super Human, and before they even get to the improv they’re amazing.

Every show is different, and every sketch within it is informed by either the theme or an audience suggestion—and sometimes by both. In an early sketch Irene Marquette plays a good old-fashioned battered housewife having her hair done by Jo Scott as a feisty self-starter. Sarah Ashley takes a seat as director in the group’s most literal sketch, while each of the other comics performs a different monologue in the voice of a Charlotte’s Web character (Boucher’s shrill, judgmental goose made me blow beer out of my nose).
