Walking Backward for Christmas?

When I was a kid my sister and I had one of those old 45rpm records of a British comedy team called "The Goons." As British comedy is wont to be, it was totally off the wall, sort of a pre-curser to Monty Python, which I am still a fan of.  This record had 4 or 5 sketches from their radio program, and our favorite was a silly song titled "I’m Walking Backward for Christmas."   The chorus of the song went like this: 

I’m walking backwards for Christmas,
Across the Irish Sea,
I’m walking backwards for Christmas,
It’s the only thing for me.

I’ve tried walking sideways,
  And walking to the front,
  But people just look at me,
  And say it’s a publicity stunt.

I’m walking backwards for Christmas,
  To prove that I love you.

I hadn’t thought of that song for years, but a couple of weeks ago, while I was visiting Tianjin for a day, I saw something that instantly made me start singing it.  I was in a car on a major highway in town–six lanes, with a huge fence in the middle.  Three lanes going one way, three lanes going the other way.  An expressway, really.  Our car was cruising the inside lane, a mere 3 or 4 feet from the divider.  In China, these big fences are put up to prevent people from crossing these 6 lane highways, an activity that is obviously death-defying.  But the only thing that people in China seem to love more than building walls and fences is finding ways over or around them, so there’s always someone either tearing a hole in the fence or clambering over it to cross the highways.  It’s not uncommon, then, to see someone standing between that inner lane and the fence looking for a break in traffic so he can get to the other side.  So I wasn’t all that surprised to look up ahead as we were driving and see a man walking in that space.  As we got closer to him, though, we realized that he wasn’t just walking on the expressway, he was walking backwards!!!  And carrying a plastic bag! 

Now I have to spend the rest of my life wondering why that man was walking backwards down the expressway, and whenever I think of him, I think of the song!
