K-Y (The Lily Savage Show)
From Tardis Wiki, the free Doctor Who reference
K-Y was The Doctor and Gayle Tuesday's pet dog.
K-Y could not traverse the small step in the TARDIS's doors, which the Doctor mocked them for, referencing the Daleks similar inability. (NOTVALID: The Lily Savage Show).
Behind the Scenes
K-Y was a parody on K9.
