Which of these is the best "Line" to use in this situation

Hey guys,
Basically I want to know which of the following would be the best sentence to use when in this situation:

There is this girl in your school/college, and you really like her and want to talk to her. She is in only one of your lessons/classes, and you have never spoke to her ever in your lesson/class. one day you get the opportunity to talk to her, she is basically walking on the street going home or whatever and you decide to talk up beside her and start talking, so which of the following would be the best line to use to start the conversation?

1: Hey, iv seen you around in school/college/class but we have never really spoke to each other, so I thought id say hi......

2: Hey, how are you?.......

3: Hi, whats up? Iv never really spoke to you before but I wanted to know some more about you.......

4: Hi, how did you find the lesson/class that we just had?......

5: Hey, whats up?..... so where you from?.......

Or if you have been in a similar situation how did you start the conversation and approach the girl?

sorry if they are a bit lame, but thats all I could think of.

Put the internet to work for you.
