What do girls do that makes guys go crazy?

okay guys what are things that girls do that make you go absolutley crazy? but in a good way, is there anything that they do so that you cant resist them? or that makes you want them and want to be around them?

A girl who is intelligent and can hold her own in conversation in many different choice topics; food to politics. And, personally, someone you can play basketball with, play music with, (sometimes) work on a car with.
A good sense of humor is always (and I believe this goes for any guy out there) something that matters a lot when dating or having a relationship.
Someone who understands and wants to learn about something that we're passionate about (this goes both ways of course).
An independent spirit. I know that sounds quite cheesy and campy. They shouldn't *need* to be around you at all times, but want to be around you. And, if they so choose to do something with some of their friends, have at it. (Vice versa.)
Self-control. Always a big thing. Knowing when to say no to any situation, when not to scream at the person who just cut them off in rush-hour traffic.
Laid back, easy going.
Ah, and for physical appearances: Straight, whiter teeth, doesn't stink, gorgeous eyes, casual non-slutty appearance.
