Using a fiendishly elaborate (and highly unnecessary) system of generating audience suggestion, Waiting for the Call invent an improvised musical based on ideas from the peculiar minds of audience members. The audience make the musical their own by selecting a combination of sketches that will generate the theme of the show, as well as adding further ideas of their own, and causing nightmarish difficulty for the improvisers in the answering of the infamous Waiting for the Call phone.
