I was watching the television today, and I saw the most idiotic commercial ever. The commercial was for a pair of HD Sunglasses. Let's look at that acronymn HD for a second: H=high, D=definition.

Now, why is this stupid? Maybe only someone with knowledge of what the term HD really means would think this is ridiculous. What is HD? High definition is a term associated to television or video broadcasts or files that are of a resolution higher than that of NTSC or PAL standards. Since real life optics have no pixel-by-pixel resolution, this makes no sense.
