That reminds me of last night's Mythbusters - might be the best ever. They were testing idioms, such as "hit the ground running" (it doesn't help). But they tried one that blew my mind: "polishing a turd." They literally collected feces from various animals at the zoo and then tried to shine the turds. It seemed hopeless until they met this dude who practiced some ancient Japanese art of rolling mud into a ball until it shines. They tried it with the poo, and lo and behold, they worked it into incredibly shiny balls! They'll never top this one.
