Jim is a gentleman who was renovating the USS Hornet in San Francisco, along with Bob. He first appears in the episode "Yogscast/ USA: Bob and Jim's Special Tour." Simon and Lewis meet him after wandering around in the restricted area of the ship. Bob tells them that they aren't supposed to be down there, but instead of kicking them out, Bob and Jim give them a tour of the bowels of the ship. It is very possible Jim is a ghost.
