Lueskelen parasta aikaa Martin Popoffin teosta "Black Sabbath - Doom Let Loose", jossa Geezer Butler muistelee "Paranoid" -albumin äänityssessioita ja tulee samalla sivunneeksi omaa suhdettaan sarjakuviin:
"I thought it was a really stupid concept. The title was from a comic book, "Iron man"... I was into English comics but not really American comics. I think Ozzy came up with the title "Iron Man". When we were writing that song, Ozzy just threw in a line about "Iron Man". It was just like a throwaway line for him, and I said, "Let's write about that" and I just made it up. I didn't really know about the comic at the time, though".
