This is easily the funniest comedy ever made.The characters are very strong - Mackay the harsh scottish guard with his neck 'twitch', Barrowclough the well-meaning and gullible guard, bumbling around pathetically, Godber the innocent and naive prisoner, and of course Norman Stanley Fletcher. Ronnie Barker's acting is superb - his expressions and timing are perfect.

The script by Dick Clement and Ian Le Frenais is one of the wittiest and sharpest ever written. For example:

(A prison inspector has just entered Fletcher's cell, and Fletcher has just made spoken to him.) Inspector: He's very articulate Mackay: Yes, like a lorry
