For $20, John Deese of Decatur County, Georgia, will sell you a bottle with a ghost in it. It's not entirely clear if he is serious about what he's selling or not. He says that he doesn't collect the spirits personally but relies on professional, er, ghostbusters. From WKMG:
“Some people will open the bottle and say they don’t get results and it’s just a fun conversation piece. Others say, ‘There’s strange things happening in my house. Where're my car keys? Where's the remote to the TV?” Deese said. “The ghost in the bottle is more toward Casper the Friendly Ghost than the Exorcist. We're kind of in the middle.”
