why do the people return to the show?

That night, the Shakespearean show is a disaster, with only twelve people showing up and none of them staying until the end. In response, the Duke prints up some new handbills touting a show titled the Royal Nonesuch. He then cleverly adds the line, "Ladies and Children Not Admitted" and comments that if such a line does not bring an audience, then he does not know Arkansas. The Royal Nonesuch opens to a house packed with men. The Duke greets them and hypes up the audience for the King.
