Amanda asked, so here's the deal:

I'm a gardener and typically go out every morning to water and weed and pick and mess around in general.  The morning I took the picture, I was in sock feet and feeling lazy, so instead of peeling off my socks, I just stuck my feet into some flipflops.  While out among the beds, I decided they needed watering (my irrigation system wasn't in yet), so I grabbed the hose and started spraying, not thinking that the soil would kick up under the spray.

I wish it was a better story, one that involved gathering sharks' teeth or sitting too close to my tootsie-warming dragon instead of being one about a lazy gardener who ruins footwear, but there you have it.
