It would seem so. He then challenged me to find anything he put on this website somewhere else on the internet.
And I did.
Then he claimed I didn't, and that I didn't follow the "rules" of his very simple challenge ("Also, I will give you $100,000 if you can find what you claim I copy and pasted anywhere on the internet or written text other than what I put on this web site.")
He hasn't declared Mayo clinic plagiarized HIM, so I can only say he must have plagiarized THEM.
Then he welched on his offer.
Reminds me of that orange guy who thinks the only way a contest is not rigged is if he wins...
