STEVE INSKEEP, HOST:
Good morning. I'm Steve Inskeep. Joseph Alexander went magnet fishing. Who knew what he might find dipping a magnet in the river in Grand Rapids, Mich. What came up looked like a hand grenade. He took it home and only after he posted pictures online did friends tell him it looked like a grenade because it was. The bomb squad took it. The grenade is German, likely from World War I. Either an American soldier brought it home or a German soldier threw it really far. Transcript provided by NPR, Copyright NPR.
