I swear by my reputation that the following is true. Although it could potentially out me, I think that's a minimal risk because it's too cool not to share.
My dad invented "Reptar."
He was inspired by me as a five year old obsessed with the Ninja Turtles and extrapolated the "little boys loving green scaly monsters " trope. As part of the "first season team," he only wrote one episode, he doesn't own the rights, but obviously his name is in the credits as the writer (for anonymity I'm not going to specify, since he co-wrote it with another writer).
I remember having a party when I was, I believe, six or seven, watching tthe episode, which was entitled "Incident in Aisle 7," a very early episode where Grandpa takes Tommy grocery shopping.
Over the years we've gotten a few free Rugrats things including a quilt, which I am currently using on my own bed
My sister even got a Reptar tattoo.
