Meet the Richardsons

A running in-joke through the first series is that Lucy Beaumont likes telling people that she has been asked to write a sitcom with the writer of "Peter Kay's Car Share (2015)", and when a person is told that, they assume she's going to be writing with Peter Kay. With some disappointment she then clarifies that the writer in question is "Tim Reid". Tim Reid did indeed co-write the first series of Car Share (2015), and further, he and Lucy co-wrote this show.
