It’s true about pretty much any TV sketch, comedy or entertainment show:
Asked what he thought of Monty Python, Eric Morecambe joked that he liked the opening and the finish. “It’s the bit in the middle I don’t like.”
Ernie Wise added: “At times there’s five or six minutes of utter boredom. And then there’s three minutes of very funny and then another eight minutes of boredom.”
Morecambe, in a towelled robe and holding a large cigar, said: “The way I feel about it is that it’s, what they give you, for want of a better expression, is university comedy. Or college comedy or whatever you want to call it. And that’s what they give you. And I’m afraid a lot of it is very unprofessional. And this irritates me being a professional.
“But what does make me laugh, really makes me laugh. And what doesn’t make me laugh, bores me stiff.”
Anyone who thinks that every moment of every MP TV show was golden wit is an idiot. There are some delightful gems in there, entirely so. Also some entire shite. Which is how the creative process goes of course.
The reason movies are often better – not just MP, but in general – is because they cost much more to make. Meaning that the script gets more of a going over. At least an attempt is made to excise the dross and create the tapestry purely from the gold.
