Teletubbies
From Tardis Wiki, the free Doctor Who reference
Teletubbies was a television programme for very young children that was popular in the United Kingdom on Earth in the late 20th and early 21st century.
The Master, after his election as Prime Minister of the United Kingdom, was seen watching an episode of Teletubbies in wonderment, marvelling at the idea of the characters having televisions in their stomachs. (DW: The Sound of Drums)
Luke Tillyard used to watch the program in his youth. (ST: Salva Mea)
