Andrex puppy
From Tardis Wiki, the free Doctor Who reference
By the mid-2000s, Madame Tussauds had a waxwork of the Andrex puppy. When the Eleventh Doctor met River Song there, she jokingly suggested that the Doctor look up the puppy and "take it for walkies". (PROSE: Suspicious Minds [+]Loading...["Suspicious Minds (short story)"])
