The uninterestingness of 12407 formed the basis of a question in the British panel game QI. In the episode "Inland Revenue," the tenth episode in Series I, broadcast 11th November, the question asked was: "What is the smallest uninteresting number?" However, guest panellist Sandi Toksvig noticed that this was a paradox because the fact that 12407 is the smallest uninteresting number is in itself interesting: 12407 (= 19 * 653) is the sum of all the numbers less than or equal to the prime 157, plus the digital root of 157 (digital root = 1+5+7 = 13; 1+3 = 4).
