Looking at the ones on the first page, I'd say the posters of said comments don't get much poon if they are even half serious about them.
The BEST pickup line is a smile and the word "Hi."
Then make small talk, ideally complimenting either the woman on her appearances or a small item she's wearing.
Flirt a little (isn't complicated or difficult) then ask for an email address or phone number after saying something along the lines of "You seem like a really interesting person. I'd like to learn more about you. Do you have a phone number or email address? Maybe we can meet for a half hour for coffee or ice cream sometime."
That's the thumbnail sketch.
If you want the full deal program, buy the book "How to Succeed with Women." If you're not getting as much as nookie as you'd like, spend $25 on this book. You'll be "the man" if you learn and apply the principles it outlines. Even if you're just an average guy - hell, even if you're in a wheelchair, apply those principles and techniques and you'll be dating ladies with model qualities if that's your thing.
Unfortunately, I learned that a lot of those total hotties are either gold diggers, ditzes or prozac poppers. Or they have eating disorders.
I certainly wish I had known about that book in my college years... But I've made up for some of that lost time these last six or seven years.
