THERE now follows a big spoiler for The Muppets. By that, I mean it is a plot spoiler for people going to see the film The Muppets, not that I am giving away motor parts to stupid cockneys.

In the film, Walter, the muppet fan of The Muppets who brings the Muppets back together, is invited to perform in the fund raising show, but he doesn’t know what he is going to do. And then, with seconds to spare, he strides onto the stage, and whistles like some sort of whistling virtuoso, accompanied by the orchestra of Muppets. It is all very heartwarming, but after the film it made me pause.

How on earth, with seconds to spare, was he able to tip off the orchestra as to what he was doing, and how could the orchestra be prepared? It is impossible. A huge logical gap in the plot.

I have to say that this was in the context of a film where puppets exist as autonomous beings and people stop in the street to sing big musical numbers. How is it that I can accept all that, but I can’t accept that an orchestra can play a piece perfectly without rehearsal?

It reminded of me of when I watched the first episode of Lois & Clark: The New Adventures Of Superman in company. We all witnessed Clark Kent fire lasers from his eyes, stop a runaway bus with his bare hands, and fly, soaring into the air like a man on wires in front of a green screen.

But when Clark introduces himself to Lois Lane as Superman, one of my companions said, “Oh, how can she not recognise him? That’s just stupid.” That was the sticking point. She could believe that a man could defy the laws of physics, but not that he could disguise himself with a pair of glasses.

So I henceforth will refer to all minor logical gaps in the context of massive suspension of disbelief as “Clark Kent’s glasses.”

So, what are your examples of “Clark Kent’s glasses?” Tweet me with #CKglasses, or use the comments below.

PS: The Muppets is great. Go and see it. Had a tear in my eye when Kermit started singing Rainbow Connection.
