Originally from Australia, Thank God You're Here is a improvisational comedy series showcasing the off-the-cuff skills of four different actors each week as they appear on a live sketch show without a script. The actors only know what costume they will be wearing and nothing else. As they enter the stage the first line they hear is "Thank God You're Here." The rest of the sketch unfolds with David Allen Grier as the host and Dave Foley as the improv judge, handing out wins quite arbitrarily.
