Robin's nest is a British sitcom starring Richard O'Sullivan as Robin Tripp, one of the lead characters in the sitcom, Man about the house, which had ended on 7 April 1976. Robin's nest aired for six series from 11 January 1977 to 31 March 1981, and co-starred Tessa Wyatt as Robin's girlfriend - and later wife - Vicky, and Tony Britton as her father. It was made by Thames Television and aired on ITV. As with its predecessors, Robin's nest also inspired an American spinoff, Three's a crowd!. John Ritter reprised his Three's company character, Jack Tripper, alongside Mary Cadorette as Vicky Bradford, Jack's girlfriend and Robert Mandan and as her father and Jack's landlord. Unlike Robin's nest, Three's a crowd! was cancelled after its first season.
