ROTFLOL!!!
After reading the title of said invention, I paused and google it and saw this:
I then read the rest of your post and saw the bit at the end and had a good laugh.
Why did I google? Well, like you, I've "invented" a few things in the past. And like you they hit me suddenly. My greatest invention happened in my sleep. It was so profound an invention that I jumped right out of bed and started drawing schematics... until something made me google it. I wasn't "going to be rich", sadly, as I was presented with hundreds of hits on Google Images of my would be invention. Turns out toilet seat shaped toilet paper was so obvious, especially to companies that had been making them for decades haha.
Lol, well it seems like you are in the same situation as me, others stealing all our good inventions! Bastards!
I came up with a magnificent one the other day. An eating utensils that is half fork, half spoon. I was going to call it a Spork. Brilliant. But...nope, someone stole my invention already. 🤨
Hahahaha. That's actually quite a good idea 😂
