I made a mistake on Professor's Name, what should I do?

I'm usually one to worry about many small things in my life. This question, is what I call preposterous.

 

People make mistakes. It's not like you didn't know his name, you just made a typographical error. He probably won't even notice it in all honesty.

 

he will actually probably hate you forever :)

 

If I were your prof, you just failed the class.

 

OK, a serious answer: this happens all the time. A brief email apologizing for the typo will help him think of you as conscientious rather than careless.

 

This is just a miss-spelling mistake, take it easy, it happens. It's not like miss-naming your prof, right! Ask me, I know.
