Men...

Alright I'm soliciting advice from people. OK, the guy that I met and thought he wasn't my type at ALL. Well he keeps trying to contact me - luckily I didn't give him my phone number, just an e-mail address. He REALLY liked me and wants to go out. I already said he reminded me of my brother (which is no compliment) in hopes that he would get the subtle rejection and not force me to tell him to get bent. It's not working. What should I do? I'm not yet ready to move to a new city and change my name and become part of the witness protection plan so something a bit less drastic is what I'm looking for.

What should I do? I don't want to be a total bitch, but I do want this yahoo to get the idea that I'm not interested in him.
