I’ve just found a funny quote that reminded me of my childhood. I’ve
seen something quite similar on my father’s notes when I was about
5. My father was a truck driver, so he probably saw that on another
truck. Here’s the one I’ve found:

Simulations are like miniskirts, they show a lot and hide the
essentials. — Hubert Kirrman

And here’s my father’s one:

Barbed wires are like miniskirts, they protect the property but
don’t block the view.

Fun, isn’t it? :)
