I invented the Skateboard in 1957

OK, Maybe not! But Really, I thought back then that this was my idea.
I had this fairly well used pair of Metal Roller Skates;

What did Melanie mean anyway -- I have a brand new Pair of Roller Skates, You have a brand new Key?
Well Anyway, I pulled apart my metal roller skates, hammered the Metal down on the heal, and then nailed them to a board.
Picture thanks to Pinterest, is not me.
Viola!! Skateboard.
Anyway, I did not get any credit for it. Maybe if my parents would have told me about patents, things would be different.
