True story, and on the complete opposite end of the spectrum, but I once made my grandmother watch Naked Lunch. I have no idea why I did this, but fumbling for answers to questions like: "What is he drinking?" and "What is that cockroach doing to that man?" made me realize what a truly poor decision maker I am. I guess I could have just flat out told her he was drinking Mugwump jism and she would have just thought that was some new fizzy drink craze the kids were into in those days, but I just.. couldn't...do it. She did recognize Roy Scheider, though. Even with the tits.
