All the above comments prove to me the difficulty of defining what makes good comedy - it's all a matter of taste and what your mood in at the time. I laughed when watching "Man about the House" and "George and Mildred" I laughed at "The Office" and " Sensitive Skin". As a teenager I did not find "Dad's Army funny - I do now.
The Jimmy James sketch "It's in the box" has made me laugh everytime I've seen it performed by Jimmy James or Jim Casey and its over 60 years old.
Comedy is a funny old thing -and that's a fact.
