Ken Froggit
From Tardis Wiki, the free Doctor Who reference
Ken Froggit was a journalist researching Earths conflicts in history at the Bodleian Library in Oxford late one night when he accidentally removed a book that was needed by the Doctor, Amy Pond and Rory Williams to jump back into reality after being trapped by a Buukvirm. Ken was only just saved in time when the Doctor was able to rejoin reality and trap the Buukvirm leaving Ken to continue his research and get on with writing his future best seller.
