You're right you know...I forgot to tell the full story.
I did indeed invent the spear but I decided not to patent that as I had not invented the patent. I did that many years later when I also invented the building, computers and office staff to work in the patent office. I was a busy caveman.
You can say that again, my friend. Now in the 21st century, you could file a complaint and claim authorship at the patent office. If they don't believe you, you invite them to take a trip in that time machine full of books and weapons that you keep in the garage.
I knew my time machine would come in handy for something! Proving how I virtually invented everything! Lol.
Don't say it too hard. They could also blame you for the bad in the world. Better leave it here, in ignorance.
