Have you ever had a good idea for a product, idea, or invention and later you saw your idea on a tv commercial or at a store, etc?

That happened to me. When I was a young mother to my infant son, he would get sick a lot and it seems I was always dealing with sheets and clothes that were soiled with sick stuff on them. I wished that the maker's of Lysol products would make detergent to put in the washer to kill the germs. Recently I've seen commercials on tv that Lysol finally came out with detergent that kills germs 44 years after I thought of it.
How about you?
