Porridge is in my top three comedys of all time.Great comedy with quality cast crammed full of funny characters.Ronnie Barker was supreme as experienced lag Fletch who is put in a cell beside first time offender Godber (played by the late Richard Beckinsale).Keeping a beady eye on them is hard task-master Mr. McKay (played by the late Fulton McKay) who has many hilarious run-ins with Fletch.The softer more gullible 'screw' is Mr.Barraclough who Fletch can wrap round his little finger.
Other great characters are the sneaky convict Ives,dyslexic 'Bunny' Warren,homosexual Lukewarm (played by Christopher Biggins),hardman Grouty (played by Peter Vaughan),a coloured Scot (played by Tony Osoba) and even a cameo role for David Jason as old lag Blanco.
They don't make them like this anymore.
