I don't know, makes perfect sense to me.
It's all about thingy A and thingy B, much like a North going Zax and a South going Zax (although, the sneeches who had stars upon thar's make a pretty good fit as well).
Now all that being said, if the chrome is falling off your bumper, you are polishing too hard, and more than likely using the wrong group of chemicals.
Which all brings me to my main point (which ties in very nicely if you ask me), which is this: If you are needing a lift on the highway, use your left thumb. I have found the left thumb to be the larger of the two.
Hope this clears it all up.
