On Monday afternoon, the Zapruder film of the Kate Middleton mystery analysis manifested on TMZ. It showed the Princess of Wales walking with her husband out of a Windsor farm shop, and while she didn’t look exactly glamorous — donning leggings and athleisure wear — she didn’t look, you know, dead, which seemed to put an end one of the more wackadoo theories on the internet: that the woman had expired, and that the royal family had spent several months cribbing from “Weekend at Bernie’s.”
