John McAfee discussing getting his security clearance when he worked for Lockheed-Martin: "They asked me very revealing questions.... Had I ever taken drugs? Yes. What kinds? Almost every kind. Uh, how much? A lot. Have you ever sold drugs? Yes. So I assumed I would never get the clearance but I did and it came in very quickly."

(clearly decades ago, and he's less than reliable, but fun nonetheless!)
