Porridge (1974)
Set in the fictional HMP Slade, this classic British comedy aired on BBC1 from 1974 to 1977, spanning three series, two Christmas specials, and a feature film. Crafted by Dick Clement and Ian La Frenais, it showcases the antics of inmates Fletcher, played by Ronnie Barker, and his young cellmate, portrayed by Richard Beckinsale.
