I’ve always wondered if people did these! I know it’s short notice, but Theatre All Around out of Manchester, NH is doing a Shakespeare flash mob later this week. They appear to be in desperate need of some bodies (as in, “if we can’t get enough people we can’t do it at all”), so if you’re in the neighborhood, get in contact and see if you can help them out! You can be “on book” so no need to worry about memorizing on short notice. You just need to be a willing body.
