Thank God You're Here (2007)

Synopsis

In this improvisational comedy competition, four guest stars walk into a live improvised comedy sketch, in which they know nothing beyond the costumes they have been given, and greeted by the line 'Thank God you're here!'. They must improvise their way through the sketch with the other actors onstage until a judge sounds a horn. The guest proclaimed the winner by judge Dave Foley takes home a cheap trophy -- and, of course, bragging rights. Based on the Australian series of the same name.
