A mock-domestic sit-com, with a lot of deeply surreal goings on behind the facade, featuring real-life husband and wife Jeremy Hardy and Kit Hollerbach, along with Paul B Davies and Caroline Leddy.  The script was co-written by the cast with Pete Sinclair (of Spitting Image and The Mark Steel Solution).  Steve Punt and Dave Cohen also contributed material for the first series.  There was a third series, for which the show was retitled At Home With The Hardys.
