Trying to find an old underground comic, 60s-80s
I'm trying to find an old American underground comic from the 1960s, 1970s, or 1980s - probably the '70s. I think it was illustrated by Robert Crumb but I could be wrong.
It's quite graphic and violent. The main character hides himself inside a robot-like device, for some reason, which is a simulacrum of a nude, beautiful woman. It's explained that the android / gynoid is a gift for the President, and the main character, on meeting the man, tries to shake his hand. But oh, no! The machine is so strong that it rips his arm off!
I don't remember much else, presumably it's part of some sort of wacky chase / battle of wits between stoners and The Man, as most of these things are. Anyhow, any help would be greatly appreciated!
