worth its weight

Maybe people should say "x is worth its weight in LSD" instead of gold:

If we look at good-quality 1 carat diamonds, we find that they are quite expensive compared to the industrial diamonds we saw earlier. Now, the diamond monopoly hasn't kept prices quite as high as LSD, however they are doing a very impressive job of trying. LSD doses measure in the micrograms, which makes the per-pound "street value" of the stuff astronomically high.

And those LZR swimsuits?

People have been saying that the new industrial grade swimsuits like the LZR Racer are worth their weight in gold. As you can see, this is clearly inaccurate. But such a suit is worth its weight in marijuana or industrial diamonds.

More fun here. (via BB)
