Why this rock is probably not a meteorite:

It's got a neat shape, but stony meteorites aren't shaped like this. There are too many protuberances and holes, and no smooth exterior anywhere.
What is it?

Can't tell from the photo; perhaps another piece of slag. It was found in a backyard near Detroit.
