A Maryland man is likely in some pain after having a toilet seat smeared with super glue removed from his backside at a hospital.  Authorities think the man may have been the unwitting victim of an April Fool's Day prank.  Emergency workers say the man got stuck to the toilet seat inside a Walmart restroom in Elkton last Thursday.  The workers had to unbolt the seat from the toilet so the man could be transported from the store to a hospital with the seat still attached.  Police consider this a second-degree assault case and are investigating.
