Behind the scenes

 * During the filming of The Ribos Operation, Tom Baker was bitten by Paul Seed's Jack Russell terrier when he tried to have it perform a trick Seed himself had done. This left Baker with a deep cut to his upper lip. As a result, publicity stills for The Ribos Operation saw him wearing a sticking plaster on his face, and for the remainder of filming Tom Baker required a heavy and uncomfortable makeup application to cover the wound. To lessen the necessary makeup coverage and explain the healing wound on-screen, a scene was added to the beginning of the following story (The Pirate Planet) wherein the Doctor strikes his face on the TARDIS console and cuts his lip. The scar remained visible for much of Season 16. (DCOM: The Pirate Planet)
