From a NYT profile of Lee Child:

He is the sort of person who carefully outlines his replies, explaining that there are three reasons for this or two causes of that, and he has a mind that’s a midden of trivia. He knows why watches in ads are always set at 8 minutes past 10, for example (too complicated to explain), and while watching the Britney Spears Pepsi commercial during the Super Bowl a few years ago, he saw instantly how “Pepsi Cola” is an anagram for “Episcopal” and “Britney Spears” an anagram for “Presbyterians.”
