Let me tell you why. You seem to think you're very tough and cool, but deep down you seem to know you're not. I inferred this from the fact that you think it's cool that you know Pidgeotto is #17, but at the same time you know you aren't that cool because your status says "Newbie".
I'm sick of people just putting whatever Pokemon they see in the person's signature or whatever their name is like. It's a bit cliche. Try and really think about what Pokemon the person's like.
