Professor?

I'm reading Carl Sagan's Demon-Haunted World: Science as a Candle in the Dark. What a book!!! If you'd like to learn more about critical thinking, you must get it. Funny is that he talks about people that don't do anything but love to call themselves "professor". He talks about a guy that bought a telescope placed on his backyard and became a sensation because he called himself professor and has claimed to be in contact with Aliens. 

What is even funnier is that I have one of these in my life now. The landlord of my house is "professor". It's amazing, he teaches guitar on the back of the house and decided that he is a professor and that his shed on the back is a college of music. Can you believe this?! My brain has a problem understanding this type of attitude, maybe it is because I am a college professor (a real one I hope) and get no joy of the title. Titles is giving based on accomplishments, right? And they are supposed to be self-satisfying not really something you freely publicize. I learned now that there must be something wrong with a person when he/she answers the cell phone: "Hello, this is Prof. A...". Eraldo and I already knew one guy at FIT who does this but at least he is a professor. My landlord is far from being one.
