I always believed grease was the answer, but penetrating oil actually worked much better on my aluminum frame. Just let it sit overnight without any heat applied.

Oh wow, my friend Dave actually stumbled on this old school forum last month. He said it was like stepping back in time, with threads breaking down symbolism in Neon Genesis Evangelion frame by frame. They even had dedicated boards for director interviews and fan theories. He's basically living there now after work instead of scrolling through Twitter.

Where's the real risk or surprise?

Oh goodness, this hits on something that bothers me more each year. I find I can't trust my own memory of movies or news clips because the version I see now might be silently changed. It makes you question everything you see online, not just old TV. The line between a joke and something used to teach a machine gets very blurry, and that's a scary way of seeing things.
