I heard he didn't retire at all, it was an imposter. The clue is the grassy knoll just behind Richo interviewing the imposter. I heard it from Elvis Presley and Britney Spears (George Bush's former secret operative) who i happened to run into at the beach while they were watching the Russian Sub return for Harrold Holt's slippers, which they just realised they'd left behind (things happen slowly in the Communist bloc). Apparently Harold was pretty desperate to have them returned to him, via sub to a sectet underground water way directly under Area 51, where a UFO piloted by Harper Lee (who gave Leonard Cohen a head job in return for the script of "To Kill A Mocking Bird"! (Some say Truman Capote really wrote that book, but that's just a crazy conspiracy theory). The UFO willl ferry them to Western Union who will deliver them to the secret (well not anymore) Fremason's base located under the Denvor International Airport, where they are preparing to depopulate the world with chemtrails and leave it for rich Jews who of course were behind the World Trade Centre Terrorist Attacks. Apparently the Fremason's Reptilian skin can't handle the hotter temperatures which apparently are real because the NOAA says so after adjusting the temperatures from the 1930's down 4 times in the last 20 years to make them look coole than today's temperatures. They wanted NASA to help do more adjusting but they were too busy getting prepared to fake another moon landing.
....................... well, anyway - that's what i heard.
