RotD: 29th October - This week in records: Most expensive sandwich, most powerful bomb detonated, largest Jack O'Lantern, oldest ghost, largest collection of Hello Kitty memorabilia, first dog in orbit, fastest roller coaster

Adam, Ben and Craig celebrate Halloween with record-breaking Jack O'Lanterns, the ghost of a dinosaur, the largest investigation into a haunted house and (in theory) the deadliest roller coaster; also up for discussion are gold-leaf sandwiches, Hello Kitty, pushing oranges with your nose and firing dogs into space.
