Just write it (before someone else writes it)

I’m not saying anyone took my ideas, because they didn’t. They just had the same ideas that I had.
I won’t go too far into how I invented the constantly variable transmission, but after dropping a sugar cone on the floor and watching it roll around a few times, there it was. I was working the counter at Farrell's Ice Cream Parlour, so they'd have probably taken my patent, anyway.

Anyhow, someone else invented it first, so I’m not going to sweat it.

The thing is that sometimes your ideas are real...
