I remember this as a kid, too! My mom said she wore a metal bra in a music video. We didn’t have MTV so I didn’t know who Madonna was, even. So I still had a bunch of questions that could’ve been solved with a Google search, had it existed.
I don’t think I got this joke until maybe a decade later when the Internet was a thing and I saw a picture or a meme or something.
I had a coworker that started to hate his job and feel trapped. We all did, but he was more vocal about it to his friends. He said:
“I think sometimes, what if I didn’t take that turn on the highway and just kept going?”.
Well one day he didn’t come in. Emailed the boss he quit later. I like to think he just kept driving on to a better future.
