The Comedy of Errors
OK, there are two set of twins. One of one set is each the servant of one of the other. No, wait... OK, there's this shipwreck and they get split up. Did I mention they were babies? Anyway many years pass and their father is in trouble. Their parents were split up as well you see. Err, where was I? Right, one twin is mistaken for the other by his servant who is himself mistaken by the first.... Ah, just come and see it. Leave your brain at the door and laugh along as the farcical hilarity ensures.
