No no no, virgins are for sacrifices… I have one tucked away for winning the lottery.
From a reliable source I've come to know a gospel choir, a Rabbi that can't hold a tune with a full set of holy scriptures, the full set of my little pony-DVD's (with player, HD-screen, a solid chair with armrests, duct-tape and toothpicks/matches), a few gallons of undiluted strawberry lemonade and a truckload of jellybeans should be enough to exorcise any supernatural hitchhiker. Do not improvise and switch the DVD's with those of barney and friends, this will only increase the risk of further possessions and/or incurable madness.
