Mmm, that's good lead

A couple homes in D.C. had lead levels several thousand times over the EPA safe limit.

But, clearly, I'm being too negative about all the lead in the water. There have to be some benefits. Like, umm... Superman won't be able to figure out where I hid those diamonds I stole, if I swallow them, because the lead in my bloodstream will block his X-ray vision.

Can you think of any benefits?
