Oh, boy. After running the plates of a suspicious vehicle and finding an outstanding arrest warrant, Birmingham police pulled over and searched the car in question. Inside the found a man, his lady friend, and a live grenade from WWII. He's been using it, he says, as a paperweight.
The bomb squad was called in, racial slurs were yelled, arrests were made. Apparently the man received the explosive when he was 16 as a gift from his grandfather, never realizing—or caring?—that it could still blow. Like, say, this other idiot's grenade bookend did.
