Numbers - 1

After his election as Prime Minister of the United Kingdom, watched an episode of Teletubbies in wonderment, marvelling at the idea of the characters having televisions in their stomachs.

The episode contained a scene of a purple Teletubby spinning around in a pink skirt, and another of the others gathering around a green Teletubby as the television in his stomach lit up. (TV: The Sound of Drums)
