David Jason starred in this 1977 ITV sitcom as Peter Barnes, a "Mr Average" character always complaining about the way the world is and doing his level best to fight red tape and bureaucracy, often to the dismay of his wife Sheila (Jacqueline Clarke).
The main protaganists each week were played by the same actors. One was Richard Wilson (who went on to play Victor Meldrew in "One Foot in the Grave", amongst other things) and the other I can't remember.
At some point in each episode one of them would of course do the proverbial tradesman's sharp intake of breath.
