Do you ladies like a guy who knows average stuff or someone who knows weird stuff?

My friends and my family always tell me I know all these weird things. My sister looks at me and says you are so "rain man" and my sister in-law says that I know all the weird things example: Last weekend I was telling my sister in-law something and hour later it was a jeopardy question which I made her answer. Then she looked at me and said that I should go on jeopardy. Another example was once at my old job one of my co-workers called me a single cell organism so I said I'm prokaryotes (group of organisms that lack a cell nucleus (= karyon), or any other membrane-bound organelles). I told him that I'm a Eukaryote (is an organism whose cells contain complex structures enclosed within membranes). He got frustrated and said you know way too much. If I don't like a girl I always say the weirdest things so she will leave me alone (just like a girl says to a guy she doesn't like that she has a boyfriend). So do ladies like guys who are average or someone who knows weird things?
