Caine later spoke of how Sellers used his impression of him as his answering machine message in the 1970s: “I called Peter one day, he wasn't in. And there was me saying, 'My name is Michael Caine. I just want you to know that Peter Sellers is not in. Not many people know that.' He invented that 'not many people know that.' And then everybody who rang him, they got me saying, 'Not many people know that.'" Over the years Caine himself had parodied his catchphrase and his "interesting facts", and has imitated others' impressions of him. In an interview with Michael Parkinson in 2007, Caine commented on the impersonations of his voice, "I can do it. 'Hello. My name is Michael Caine. Not many people know that.' I sound like a bloody moron. You know where they've got me now? On birthday cards. 'It's your birthday today. Not many people know that'. Now they've got me on Satellite navigation. It's me going, 'take the second turn on the right, and you'll wind up right in the shit.'" In 1983, Caine used his "not a lot of people know that" phrase as a joke in the film "Educating Rita".
