Fletch: When Harry Grout asks a favour of you, it is on the express understanding that favour gets done. Otherwise he takes it as a personal insult, and send round a henchman to mete out dire retribution. From Crusher With Love.
There was an American version of this classic UK show. It was titled On the Rocks. The script was reworked in order to make the style of humour suit the audience. It lasted one series before being cancelled in May '76.
