A similar pun shows up in the title of the 2007 series episode "Smith and Jones", with the Tenth Doctor and new companion Martha Jones.
The Fifth Doctor's sequence in the novel The Eight Doctors – featuring the Eighth Doctor going through his own past to meet and assist his other selves – takes place after this episode, the Fifth Doctor travelling to the Eye of Orion to continue their earlier holiday only to be attacked by a renegade Time Lord from the Eighth Doctor's era using the Timescoop, forcing the two Doctors to defeat a Raston Warrior Robot and a Sontaran squadron.
