Secrets of attracting women by making them laugh at any time, any place, and any way you want till they fall in love with you.

Psychological studies have shown that during an initial contact, it's psychologically impossible to dislike someone who has made you laugh genuinely for 5 times or more. (According to my experience, the word "dislike" should be replaced by "resist the attraction of".)
Think about it. It's basic human nature to avoid pain and gain pleasure. What do we do when we experience pleasure? We smile or laugh! Laughter means pleasure, and humor is what creates laughter.
