WTF is this??

OK, someone needs to tell me WTF kind of plant/weed/bush this is.  Bob found it growing next to the barn while he was out splitting logs one day. It's weird looking, with spiky leaves, big spiky green "pods" (you can see them if you look closely), and big pink flowers. At first I thought it was some alien weed I'd never seen before, but then I saw it in someone's front yard as I was driving to the grocery store.  So, anyone have any ideas?

UPDATE:  I'm told this is Datura stramonium, AKA Jimson Weed.  Interesting....
