“When I was working with Debbie Reynolds for the second time [Ed. note: it was actually for the first time, at least as far as I know!] (in The Second Time Around, a western comedy) at 20th Century Fox, a fellow came up to me and complimented me on my acting. He said he was a composer and the guy he came with, his next door neighbor, played the guitar. I said, ‘What’s your name?’ He said, ‘Frank Zappa.’ So I said, ‘OK, I have something for you. We have no music for The World’s Greatest Sinner. If you can supply the orchestra and a place to tape it, you have the job.’ And that’s what he did. Around the same time he was on the Steve Allen Show. That’s where our friendship stopped. Steve asked him what films he did. He said, ‘I did The World’s Greatest Sinner, the world’s worst film and all the actors were from skid row.’ It wasn’t true. The press said I was the world’s greatest ham, and that The World’s Greatest Sinner was a travesty of the arts. Zappa didn’t like that and he started to get on their bandwagon. The opening night at the director’s guild, he was in complete awe. He walked into the window and banged himself in the head. He didn’t even know there was a window there.”
